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…
Far beyond the Sun: III. The magnetic cycle of Horologii
Julián D. Alvarado-Gómez, Gaitee A. J. Hussain, Eliana M. Amazo-Gómez +6
We present a comprehensive investigation of the magnetic cycle of the young, active solar analogue Horologii ( Hor) based on intensive spectropolarimetric monitoring using…
Exploring coronal abundances of M dwarfs at moderate activity levels
J. J. Chebly, K. Poppenhäger, J. D. Alvarado-Gómez +1
Main sequence stars of spectral types F, G, and K with low to moderate activity levels exhibit a recognizable pattern known as the first ionization potential effect (FIP effect), w…
