Magnetic activity in cool stars: manifestations and relevance to exoplanets
E. Işık, 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…
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…
The corona of a fully convective star with a near-polar flare
Ekaterina Ilin, Katja Poppenhäger, Beate Stelzer +1
In 2020, the Transiting Exoplanet Survey Satellite (TESS) observed a rapidly rotating M7 dwarf, TIC 277539431, produce a flare at 81° latitude, the highest latitude flare located t…
The Great Dimming of Betelgeuse: the photosphere as revealed by tomography over the past 15 years
Daniel Jadlovský, Thomas Granzer, Michael Weber +6
Betelgeuse, a red supergiant star of semi-regular variability, reached a historical minimum brightness in February 2020, known as the Great Dimming. Even though the brightness has…
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…
Searching for flaring star-planet interactions in AU Mic TESS observations
Ekaterina Ilin, Katja Poppenhäger
Planets that closely orbit magnetically active stars are thought to be able to interact with their magnetic fields in a way that modulates stellar activity. This modulation in phas…
