Searching for rotational X-ray modulation on TIC 277539431
Desmond Dsouza, Katja Poppenhaeger, Ekaterina Ilin
TIC 277539431, a fast rotating M7 dwarf, was detected to host the highest latitude flare to date at . Magnetic activity like stellar flares occurring at high latitude ind…
Close-in planet induces flares on its host star
Ekaterina Ilin, Harish K. Vedantham, Katja Poppenhäger +4
In the past decade, hundreds of exoplanets have been discovered in extremely short orbits below 10 days. Unlike in the Solar System, planets in these systems orbit their host stars…
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…
Three young planets around the K-dwarf K2-198: High-energy environment, evaporation history and expected future
Laura Ketzer, Katja Poppenhaeger, Martina Baratella +1
Planets orbiting young stars are thought to experience atmospheric evaporation as a result of the host stars' high magnetic activity. We study the evaporation history and expected…
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…
Flaring Latitudes in Ensembles of Low Mass Stars
Ekaterina Ilin, Ruth Angus, Rodrigo Luger +2
The distribution of small-scale magnetic fields in stellar photospheres is an important ingredient in our understanding of the magnetism of low mass stars. Their spatial distributi…
Lower-than-expected flare temperatures for TRAPPIST-1
A. J. Maas, E. Ilin, M. Oshagh +12
Although high energetic radiation from flares is a potential threat to exoplanet atmospheres and may lead to surface sterilization, it might also provide the extra energy for low-m…
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…
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…
Localizing flares to understand stellar magnetic fields and space weather in exo-systems
Ekaterina Ilin, Katja Poppenhäger, Julián D. Alvarado-Gómez
Stars are uniform spheres, but only to first order. The way in which stellar rotation and magnetism break this symmetry places important observational constraints on stellar magnet…
Giant white-light flares on fully convective stars occur at high latitudes
Ekaterina Ilin, Katja Poppenhaeger, Sarah J. Schmidt +7
White-light flares are magnetically driven localized brightenings on the surfaces of stars. Their temporal, spectral, and statistical properties present a treasury of physical info…
Flares in Open Clusters with K2. II. Pleiades, Hyades, Praesepe, Ruprecht 147, and M67
Ekaterina Ilin, Sarah J. Schmidt, Katja Poppenhäger +3
Flares, energetic eruptions on the surfaces of stars, are an unmistakable manifestation of magnetically driven emission. Their occurrence rates and energy distributions trace stell…
MALDI-TOF and Quantum Chemical Study of Non-stoichiometric Tantalum Oxychloride Clusters
E. G. Ilin, A. S. Parshakov, V. G. Yarzhemsky +2
Using the MALDI-TOF spectroscopy method, clusters of non-stoichiometric tantalum oxychlorides formed as a result of hydrolysis of nanoscale reaction products of tantalum pentachlor…
Flares in Open Clusters with K2. I. M45 (Pleiades), M44 (Praesepe) and M67
Ekaterina Ilin, Sarah J. Schmidt, James R. A. Davenport +1
The presence and strength of a stellar magnetic field and activity is rooted in a star's fundamental parameters such as mass and age. Can flares serve as an accurate stellar "clock…
