Magnetic activity in cool stars: manifestations and relevance to exoplanets
E. IÅık, A. Valio, A. Strugarek +10
Understanding stellar magnetic activity is central to exoplanet science in two ways: it sets the dynamic astrospheric boundary condition governing planetary space environments, and…
X-ray Emission and Stellar Ages of Sun-Like Stars
Breanna A. Binder, Edward W. Schwieterman, Alison Farrish +4
We present an analysis of XMM-Newton and Chandra observations of 85 nearby main-sequence FGK stars with age estimates ranging from 0.2-12 Gyr. We measure quiescent 0.3-10 keV lumin…
Stellar Coronal Mass Ejections with HWO: A Science Case Concept
R. O. Parke Loyd, James Paul Mason, Ivey Davis +3
The primary mission of the Habitable World Observatory (HWO) will be to constrain the prevalence of life on Earth-like planets. These planets will be subject to impacts by energeti…
The Exospace Weather Frontier
R. O. Parke Loyd, Evgenya L. Shkolnik, Joseph Lazio +26
Space weather is among the most powerful and least understood forces shaping planetary atmospheres. In our Solar System, we observe its effects directly: atmospheric escape, chemic…
