Star Planet Interactions
Arghyadeep Paul, Kristina Kislyakova, Manuel Güdel +13
Star-planet interactions (SPIs) describe the continuous exchange of energy, momentum, and mass between exoplanets and their host stars through radiative, tidal, magnetic, and parti…
Stellar Forcing of (exo)Planetary Environments
Julián D. Alvarado-Gómez, Erika Palmerio, Manuel Güdel +13
The environments of exoplanets are fundamentally shaped by the magnetic activity of their host stars through radiative, plasma, and particle-driven processes. This article presents…
Long-term X-ray variability of the multiple-planet host L 98-59: Hints of an activity cycle
I. Pillitteri, S. Bellotti, S. Benatti +7
High-energy irradiation in X-rays and UV (XUV) can transform the planetary atmospheres through photoevaporation and photochemistry. This is more crucial for M stars, whose habitabl…
First Resolution of a Main Sequence G-Star Astrosphere Using Chandra
C. M. Lisse, S. J. Wolk, B. Snios +24
We report resolution of a halo of X-ray line emission surrounding the Zero Age Main Sequence (ZAMS) G8.5V star HD 61005 by Chandra ACIS-S. Located only 36.4 pc distant, HD 61005 is…
X-ray detection of astrospheres around three main-sequence stars and their mass-loss rates
K. G. Kislyakova, M. Güdel, D. Koutroumpa +3
Stellar winds of cool main sequence stars are very difficult to constrain observationally. One way to measure stellar mass loss rates is to detect soft X-ray emission from stellar…
Non-thermal motions and atmospheric heating of cool stars
S. Boro Saikia, T. Lueftinger, V. S. Airapetian +6
The magnetic processes associated with the non-thermal broadening of optically thin emission lines appear to carry enough energy to heat the corona and accelerate the solar wind. W…
