Simultaneous eROSITA and TESS observations of the ultra-active star AB~Doradus
J. H. M. M. Schmitt, P. Ioannidis, J. Robradel +3
We present simultaneous multiwavelength observations of the ultra-active star AB~Doradus obtained in the X-ray range with the eROSITA instrument on board the Russian--German Spectr…
Keeping up with the cool stars: One TESS year in the life of AB Doradus
P. Ioannidis, J. H. M. M. Schmitt
The long-term, high precision photometry delivered by the Transiting Exoplanet Survey Satellite (TESS) enables us to gain new insight into known and hitherto well-studied stars. In…
Starspot evolution, Differential Rotation and Correlation between Chromospheric and Photospheric Activities on Kepler-411
Fukun Xu, Shenghong Gu, Panogiotis Ioannidis
We present an analysis of the starspot evolution, the surface differential rotation (SDR), the correlation between chromospheric activity indicators and the spatial connection betw…
Kepler-411: a four-planet system with an active host star
Leilei Sun, P. Ioannidis, Shenghong Gu +3
We present a detailed characterization of the Kepler-411 system (KOI 1781). This system was previously known to host two transiting planets: one with a period of 3 days ($R=2.4R_\o…
