Spectroscopy of flares on AU Mic
P. Odert, M. Leitzinger, P. Kabáth +6
Photometric space missions like Kepler and TESS have revealed unprecedented statistics of stellar flares, including the frequent detection of highly energetic superflares. Spectros…
Spectroscopic investigation of the southern late-K/early-M dwarf binary CC Eri
M. Leitzinger, P. Odert, R. Greimel +6
In the recent past investigations of stellar Coronal Mass Ejections (CMEs) and flares/superflares gained special attention because of their relevance for planetary habitability and…
Flares and superflares on the southern active binary CC Eri
M. Leitzinger, P. Odert, R. Greimel +15
Flares and CMEs are known to be the dominating high-energy phenomena on cool stars. Superflares were thoroughly investigated using broadband photometry predominantly from Kepler, K…
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…
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…
Observations and detectability of young Suns' flaring and CME activity in optical spectra
M. Leitzinger, P. Odert, R. Greimel
The Sun's history is still a subject of interest to modern astrophysics. Observationally constrained CME rates of young solar analogues are still lacking, as those require dedicate…
