Relativistic objects in astrophysics present a diverse set of phenomena and cover vast ranges of time scales and spatial scales, but their descriptions rely on a similar backbone: production of a relativistic outflow in a central compact object and dissipation of the outflow at large radii, accompanied by acceleration of particles up to very high energies and production of secondary non-thermal electromagnetic radiation. This book provides a timely and comprehensive review of the main physical processes involved in the formation and dissipation of relativistic outflows. It will be particularly useful to postgraduate students and researchers active in various areas of astrophysics and space science¿.

This volume presents a broad overview of the requirements, capabilities, challenges and future directions of spaceborne imaging spectroscopy to explore the Earth¿s surface for a range of application domains. These include mine exploration, soil mapping, vegetation monitoring, mapping of pollution and hazardous materials, inland and coastal water monitoring, urban applications and others. Imaging spectroscopy, also often termed hyperspectral remote sensing, for terrestrial Earth observation dates back to the 1980s, when the first spectrometers observing in the visible to shortwave infrared wavelength range were deployed on airborne platforms. From the end of the 1990s onwards, spaceborne hyperspectral missions have demonstrated the capability to provide information on the composition and biochemical and physical characteristics of the Earth¿s surface. Today, several hyperspectral spaceborne missions are under development to be launched within the next few years. It can be expected that future global and frequent coverage of the Earth¿s surface with spaceborne imaging spectroscopy data will bring a major advance in the information depth that future Earth system models and monitoring service developments can be based on.

This topical volume reviews a comprehensive set of problems raised by the use of Gamma Ray Bursts (GRBs) as cosmological probes, as they were addressed and debated during the ISSI-Beijing workshop "Gamma Ray Bursts: A Tool to Explore the Young Universe," which took place from April 13 to 17, 2015, in Beijing. The invited authors represent both the GRB community stricto sensu and the community studying high-redshift galaxies and star formation history. The chapters of the book elucidate the connection between GRBs and the deep universe, stimulating thoughts on how to develop worldwide synergies between high-redshift GRB studies and surveys of the deep universe.

This volume discusses the evolutionary paths linking planets and their atmospheres to their origin within circumstellar disks. Dust accretion within disks generates planet cores, while gas accretion on these cores leads to the diversity of their fluid envelopes.
In the past 50 years, our understanding of the origin and evolution of the Solar System has grown exponentially, in large part due to the availability of meteorites and the success of sample return missions.
The review papers in this volume provide an in-depth examination of complex astrophysical phenomena of star formation via multi-wavelength observations and modeling. Among the fundamental issues discussed in the book are: The role of gravity and magnetized turbulence in the formation and evolution of molecular cloudsThe stellar feedback (supernovae, HII regions, winds, cosmic rays) in regulating star formation The origin of the stellar initial mass function and its universality across various environments Jets, magnetic fields and high energy particles in stellar clustersThe origin of the first stars and black holesThe goal of these papers is to review the major processes governing star formation and to investigate how they are interlinked. In doing so, they provide an in-depth look at the tremendous theoretical and observational progress that has been made in the recent past and also outline future perspectives.Previously published in Space Science Reviews in the Topical Collection "Star Formation¿
The present sixth volume of ISSI Space Sciences Series is the outcome of the most ambitious study project of ISSI hitherto, that on 'Source and Loss Processes of Magnetospheric Plasma'. The goal has been to produce a fully integrated book on the subject, which gives an authoritative overview of all aspects of the topic in a well organized form, useful and readable both for active researchers in the field and for young scientists who are starting their research in space physics. In order to represent the full diversity of experience and perspective that exists in the science community, some 50 leading scientists from allover the world were invited to participate in the project and contribute to the text. With the scientific competence well in hand, the dominating problem in producing the book has been to achieve a degree of consistency in style, nomenclature, notations and format, as well as good cross referencing. To what degree we have succeeded in reaching our goal of delivering a volume that will be useful to the community in both its comprehensiveness and readability remains to be decided by the readers. The book is the outcome of a three year long process. In December 1995 the study project on 'Source and Loss Processes of Magnetospheric Plasma' was se- lected by ISSI after consultations with several groups of senior representatives of the space physics community.

They discuss how these factors contribute to our understanding of accretion timescales, volatile delivery, the origin of the Moon and the evolution of atmospheres and water inventories of terrestrial planets. Also explored are plate tectonic formation, the origin of nitrogen atmospheres and the prospects for exoplanet habitability.The papers are forward-looking as well, considering the importance of future space missions for understanding terrestrial planet evolution in the Solar System and beyond. Overall, this volume shall be useful for academic and professional audiences across a range of scientific disciplines.Previously published in Space Science Reviews in the Topical Collection "Reading Terrestrial Planet Evolution in Isotopes and Element Measurements"
This volume provides an overview of the fast-developing field of tidal disruption events. For several decades, astronomers speculated that a hapless star could wander too close to a massive black hole and be torn apart by tidal forces. Yet it is only with the recent advent of wide-field transient surveys that such events have been detected.Written by a team of prominent researchers, the chapters detail the discoveries made so far in this burgeoning field of study across the entire electromagnetic spectrum, from gamma-rays through X-rays, ultra-violet, optical, infrared, and radio. In addition, they show how tidal disruption events can be used to study the properties of otherwise undetectable supermassive black holes; the populations and dynamics of stars in galactic nuclei; the physics of black hole accretion, including the potential to detect relativistic effects near a SMBH; and the physics of (radio) jet formation and evolution in a pristine environment.Finally,the book outlines important outstanding questions about TDEs. With more than 100 color images, the volume will be useful to researchers and others interested in learning more about this promising area of astrophysics.Previously published in Space Science Reviews in the Topical Collection ¿The Tidal Disruption of Stars by Massive Black Holes¿
The Sentinel missions of the COPERNICUS Programme of the European Union, as well as other Earth Observation missions, provide new opportunities for systematic monitoring of natural and man-made hazards and disasters that can highly impact human societies.The contributions collected in this book address a broad range of geohazards observable from space, including earthquakes, volcanic hazards, extreme events (e.g. storm surges, floods and droughts), fires, pollution, tipping points in physical and biological systems, etc.. They provide information on how space observations can improve our understanding of the driving mechanisms at the origin of such geohazards, and of their mutual interactions. Focus is given on the expected added-value information obtained by combining different types of space-based and in situ observations as well as model results.The chapters "Space-Based Earth Observations for Disaster Risk Management", "Earth Observation for theAssessment of Earthquake Hazard, Risk and Disaster Management", "Earth Observation for Crustal Tectonics and Earthquake Hazards", "Earth Observations for Monitoring Marine Coastal Hazards and Their Drivers", "Air Pollution and Sea Pollution Seen from Space" are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.Previously published in Surveys in Geophysics, Volume 41, Issue 6, 2020

"The Heliosphere in the Local Interstellar Medium", the Proceedings of the First ISSI Workshop 6-10 November 1995, Bern, Switzerland, edited by R. von Steiger, R. Lallement, and M.A. Lee and published in 1996, was the first International Space Science Institute (ISSI) book in the Space Sciences Series. This book covers the knowledge gained in the subsequent 27 years that revolutionized our understanding of the interaction of the heliosphere with the very local interstellar medium (VLISM). Entirely new regions of space have been explored! The Voyagers both crossed the termination shock, passed through the heliosheath, crossed the heliopause, and entered the interstellar medium. New Horizons was launched with more modern instrumentation and explores low-latitude regions of the outer heliosphere. Energetic neutral atoms observed by IBEX and CASSINI allowed exploration of the heliosphere over the whole sky. The initial reconnaissance of the heliosphere and VLISM is complete with in situmeasurements, observations of energetic neutral atoms (ENAs), neutral VLISM H and He, UV emissions, and interstellar dust.This book is a collection reviews from experts in the many aspects of this field that describe the current state of knowledge of the heliosphere¿s interaction with the interstellar medium, puzzles yet to be solved, and future plans to continue these studies.
The book presents a broad and in-depth overview of recent achievements and the current state of research in magnetohydrodynamic (MHD) oscillatory and wave phenomena in the coronae of the Sun and stars. Major progress in coronal wave studies has been achieved thanks to the combination of high-precision multi-wavelength observations with spaceborne and ground-based facilities, elaborated theory of the interaction of MHD waves with plasma non-uniformities, state-of-the-art numerical simulations, and novel data analysis techniques. It has allowed the research community to reach a new look at the role played by MHD wave processes in the enigmatic phenomena of coronal plasma heating and wind acceleration as well as powerful energy releases such as flares and coronal mass ejections. In addition, the waves are intensively used as natural probes in the remote diagnostics of the coronal plasma parameters and physical processes operating in solar and stellar coronae via the method of MHD seismology. Individual chapters cover recent cutting-edge results obtained on the analysis and theoretical modelling of several most intensively studied coronal MHD wave phenomena, namely, kink and sausage oscillations of coronal loops and other field-aligned plasma structures, plus running and standing slow magnetoacoustic waves. A dedicated chapter assesses the reliability of proposed theoretical mechanisms for heating of the coronal plasma by MHD waves. Another chapter summarizes the current state of our understanding of the physical mechanisms and observational properties of quasi-periodic pulsations in solar flares, considers their analogy with similar processes detected in stellar flares, and thus establishes solid ground for the further exploitation of the solar-stellar analogy. An important discussion of novel data analysis techniques designed recently for MHD seismology applications is presented in a devoted chapter. The direction of future advances in the designated research areas are discussed.The book is a spin-off from the Topical Collection "Oscillatory Processes in Solar and Stellar Coronae" of the journal Space Science Reviews.
