PLATOSpec's first results: planets WASP-35b and TOI-622b are on aligned orbits, and K2-237b is on a polar orbit
J. Zak, P. Kabath, H. M. J. Boffin +10
The spin-orbit angle between a stellar spin axis and its planetary orbital axis is a key diagnostic of planetary migration pathways, yet the mechanisms shaping the observed spin-or…
Spectroscopic observations of flares and superflares on AU Mic
P. Odert, M. Leitzinger, R. Greimel +13
The young active flare star AU~Mic is the planet host star with the highest flare rate from TESS data. Therefore, it represents an ideal target for dedicated ground-based monitorin…
Two Earth-size Planets and an Earth-size Candidate Transiting the Nearby Star HD 101581
Michelle Kunimoto, Zifan Lin, Sarah Millholland +43
We report the validation of multiple planets transiting the nearby ( pc) K5V dwarf HD 101581 (GJ 435, TOI-6276, TIC 397362481). The system consists of at least two Earth-…
Gaia21bty: An EXor lightcurve exhibiting an FUor spectrum
Michał Siwak, Lynne A. Hillenbrand, Ágnes Kóspál +16
Gaia21bty, a pre-main sequence star that previously had shown aperiodic dips in its light curve, underwent a considerable mag brightening that occurred over a few mo…
EPIC 206197016: A very hot white dwarf orbited by a strongly irradiated red dwarf
J. Krticka, A. Kawka, Z. Mikulasek +7
Very precise satellite photometry has revealed a large number of variable stars whose variability is caused either by surface spots or by binarity. Detailed studies of such variabl…
HD 60431, the CP2 star with the shortest rotational period -- Physical parameters and period analysis
Z. Mikulasek, E. Semenko, E. Paunzen +5
CP2 stars show periodic photometric, spectroscopic, and magnetic variations with the rotational period. They are generally slow rotators, with rotational periods exceeding half a d…
