As exoplanets acquire material and grow to the final size, their atmospheres are subjected to intense UV and X-radiation and high-energy particle bombardment from the young host star. Whether a planet can retain its atmosphere and the conditions for significant mass loss both depend upon the strength of the host star's high-energy radiation and wind, the distance of the exoplanet from its host star, the gravitational potential of the exoplanet, and the initial chemical composition of the exoplanet atmosphere. This introductory overview describes the physical processes responsible for the emission of radiation and acceleration of winds of host stars that together control the environment of an exoplanet, focusing on topics that are critically important for understanding exoplanetary atmospheres but are usually not posed from the perspective of host stars. Accordingly, both host stars and exoplanets are not studied in isolation but are treated as integrated systems. Stellar magnetic fields, which are the energy source for activity phenomena including high-energy radiation and winds, play a critical role in determining whether exoplanets are habitable. This text is primarily for researchers and graduate students who are studying exoplanet atmospheres and habitability, but who may not have a background in the physics and phenomenology of host stars that provide the environment in which exoplanets evolve. It provides a comprehensive overview of this broad topic rather than going deeply into many technical aspects but includes a large list of references to guide those interested in pursuing these questions. Nonspecialists with a scientific background should also find this text a valuable resource for understanding the critical issues of contemporary exoplanet research. 410 0$aLecture Notes in Physics,$x0075-8450 ;$v955 606 $aPlanetary science 606 $aAstrobiology 606 $aAtmospheric sciences 606 $aPlanetology 606 $aSolar system 606 $aSpace sciences 606 $aPlanetary Sciences$3https://scigraph.springernature.com/ontologies/product-market-codes/P22060 606 $aAstrobiology$3https://scigraph.springernature.com/ontologies/product-market-codes/P22057 606 $aAtmospheric Sciences$3https://scigraph.springernature.com/ontologies/product-market-codes/G36000 606 $aPlanetology$3https://scigraph.springernature.com/ontologies/product-market-codes/G18010 606 $aSolar and Heliospheric Physics $3https://scigraph.springernature.com/ontologies/product-market-codes/P22070 606 $aSpace Sciences (including Extraterrestrial Physics, Space Exploration and Astronautics)$3https://scigraph.springernature.com/ontologies/product-market-codes/P22030 615 0$aPlanetary science. 615 0$aAstrobiology. 615 0$aAtmospheric sciences. 615 0$aPlanetology. 615 0$aSolar system. 615 0$aSpace sciences. 615 14$aPlanetary Sciences. 615 24$aAstrobiology. 615 24$aAtmospheric Sciences. 615 24$aPlanetology. 615 24$aSolar and Heliospheric Physics . 615 24$aSpace Sciences (including Extraterrestrial Physics, Space Exploration and Astronautics). 676 $a523.82 700 $aLinsky$b Jeffrey$4aut$4http://id.loc.gov/vocabulary/relators/aut$047355 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996466806503316 996 $aHost Stars and their Effects on Exoplanet Atmospheres$92530728 997 $aUNISA
