Overview

This comprehensive introductory overview describes the emission of radiation (X-rays to radio) and the winds of host stars and how they control the past, present, and future evolution of an exoplanet. The book focuses on topics that are critically important for understanding exoplanet atmospheres but are often posed without a comprehensive and detailed understanding of the host star and its effects on the exoplanet. Although both stars and exoplanets are usually studied in isolation, in this book they are treated as an integrated system. Whether or not an exoplanet can retain its atmosphere and the chemical composition of the atmosphere depends critically on the strength, time dependence, and spectral energy distribution of the host star's radiation, flares, coronal mass ejections, and wind, which are described in detail in the book. The book describes the roles played by magnetic fields in the coronae and chromospheres of host stars that tie together stellar active phenomena with major effects on exoplanet atmospheres. In the era of JWST and very sensitive ground- and space-based instruments, a critical topic is the noise imposed on radial velocity measurements and transit photometry and spectroscopy by the host star's activity and variability that fundamentally limit our understanding of exoplanet properties. This topic is addressed in detail in the book. This book is written primarily for graduate students and researchers who are studying exoplanet atmospheres and habitability, but who may not have a background in the physics and phenomenology of host stars. The book could serve as a reference book for graduate level classes on exoplanets. Nonspecialists with a scientific background should also find this text a valuable resource for understanding the critical issues of contemporary exoplanet research. This new edition of “Host Stars and their Effects on Exoplanet Atmospheres"" is a major revision of the existing book in the following ways: It includes a new discussion of how stellar noise fundamentally limits our understanding of exoplanet atmospheres It demonstrates in detail how stellar activity acts as fundamental driver of exoplanet atmosphere evolution It provides an outlook on how the field of exoplanet atmospheres and bio-astrophysics is being driven by powerful new telescopes and instruments It extensively updates many chapters, in particular concerning host star extreme- and far-ultraviolet emission, stellar winds, stellar surface structures, the effects of space weather on exoplanets, and provides a realistic evaluation of habitability taking into account the evolution of host star activity.

Author Information

The American Astronomical Society recently honored Jeffrey Linsky as a Fellow of the AAS ""for decades of innovative studies of the heliosphere and the local interstellar medium; for his models of stellar chromospheres, for productive observing programs on multiple satellites and for establishing the deuterium-to-hydrogen ratio in the local disk, among other scientific contributions, and for his decades of service to the astronomical community."" He has played a very active role in establishing the scientific objectives of numerous NASA telescopes including the Far Ultraviolet Spectrograph Observatory (FUSE), Chandra X-ray Observatory, and the Hubble Space Telescope (HST) including being on the science teams that designed the High Resolution Spectrograph (HRS), the Space Telescope Imaging Spectrograph (STIS), and the Cosmic Origins Spectrograph (COS). He has served on many advisory groups for NASA including peer review panels and science advisory groups for various missions and has served on two Senior Review Panels for NASA. His research covers the topics of stellar chromospheres, stellar coronae, stellar winds, exoplanet atmospheres, and the local interstellar medium. He has published 407 peer reviewed papers (H-index = 88) in the astrophysical journals, has written one book (Host Stars and their effects on Exoplanet Atmospheres) and edited five others, and has written a number of review papers on these topics. He is often asked to be an invited speaker at scientific conferences in these fields. His research and publications are described in his website jila.colorado.edu/~jlinsky/. His CV is included in the website under the topic ""Biography"".
