First Doppler image and starspot-corrected orbit for Andromedae: A multifaceted activity analysis
Ã. Adebali, K. G. Strassmeier, I. V. Ilyin +3
We quantify the effect of starspots for the orbital elements of the spotted RS CVn binary Andromedae ( And) and present an empirical correction. The aim is to obtain a mor…

Stellar flares, superflares and coronal mass ejections -- entering the Big data era
Krisztián Vida, Zsolt KÅvári, Martin Leitzinger +6
Flares, sometimes accompanied by coronal mass ejections (CMEs), are the result of sudden changes in the magnetic field of stars with high energy release through magnetic reconnecti…
