TL;DR: In this article, a panchromatic (X-ray to mid-IR) study of the spectral energy distribution (SED) of 11 nearby planet-hosting stars is performed, based on the measurements of the Ultraviolet Spectral Characteristics of Low-mass Exoplanetary Systems (MUSCLES) survey.
Journal ArticleDOI
The Ultraviolet Radiation Environment around M Dwarf Exoplanet Host Stars
Cynthia S. Froning,Jeffrey L. Linsky,Aki Roberge,John T. Stocke,Feng Tian,Rachel Bushinsky,Jean-Michel Desert,Pablo J. D. Mauas,Mariela Vieytes,Lucianne M. Walkowicz +9 more
TL;DR: The spectral and temporal behavior of exoplanet host stars is a critical input to models of the chemistry and evolution of planetary atmospheres using observations from the Hubble Space Telescope as discussed by the authors.
Journal ArticleDOI
High stellar FUV/NUV ratio and oxygen contents in the atmospheres of potentially habitable planets
TL;DR: In this article, the atmospheric oxygen contents (O2 and O3) of potentially habitable planets in this type of UV environment could be 2-3 orders of magnitude greater than those of their counterparts around Sun-like stars as a result of decreased photolysis of O3, H2O2, and HO2.
Journal ArticleDOI

TL;DR: In this paper, the authors used the equivalent width of the chromospheric Ca II K line at 3933 Angstroms, when corrected for spectral type, to estimate the stellar surface flux in ultraviolet emission lines, including H I Lyman alpha.
