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 H…

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…

Planetary perturbers: Flaring star-planet interactions in Kepler and TESS

Ekaterina Ilin, Katja Poppenhäger, Judy Chebly +2

In many star-planet systems discovered so far, the innermost planet orbits within only a few stellar radii. In these systems, planets could become in-situ probes of the extended st…

Numerical quantification of the wind properties of cool main sequence stars

Judy Chebly, Julián D. Alvarado-Gómez, Katja Poppenhäger +1

As a cool star evolves, it loses mass and angular momentum due to magnetized stellar winds which affect its rotational evolution. This change has consequences that range from the a…

Quantification of the environment of cool stars using numerical simulations

J. J. Chebly, J. D. Alvarado-Gómez, K. Poppenhaeger

Stars interact with their planets through gravitation, radiation, and magnetic fields. Although magnetic activity decreases with time, reducing associated high-energy (e.g., corona…

Simulating the Space Weather in the AU Mic System: Stellar Winds and Extreme Coronal Mass Ejections

Julián D. Alvarado-Gómez, Ofer Cohen, Jeremy J. Drake +7

Two close-in planets have been recently found around the M-dwarf flare star AU Microscopii (AU Mic). These Neptune-sized planets (AU Mic b and c) seem to be located very close to t…

Destination exoplanet: Habitability conditions influenced bystellar winds properties

Judy J. Chebly, Julián D. Alvarado-Gómez, Katja Poppenhaeger

The cumulative effect of the magnetized stellar winds on exoplanets dominates over other forms of star-planet interactions. When combined with photoevaporation, these winds will le…
