Brightness and mass accretion rate evolution during the 2022 burst of EX~Lupi
F. Cruz-Sáenz de Miera, Á. Kóspál, P. Ábrahám +18
EX Lupi is the prototype by which EXor-type outbursts were defined. It has experienced multiple accretion-related bursts and outbursts throughout the last decades, whose study have…
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…
The Gaia alerted fading of the FUor-type star Gaia21elv
Zsófia Nagy, Sunkyung Park, Péter Ábrahám +26
FU Orionis objects (FUors) are eruptive young stars, which exhibit outbursts that last from decades to a century. Due to the duration of their outbursts, and to the fact that only…
The view of the Cepheus OB2 association
Máté Szilágyi, Mária Kun, Péter Ábrahám +1
OB associations, birthplaces of the most luminous stars, are key objects for understanding the formation of high-mass stars and their effects on their environments. The aim of this…
Photometric and spectroscopic study of the EXor-like eruptive young star Gaia19fct
Sunkyung Park, Ágnes Kóspál, Péter Ábrahám +19
Gaia19fct is one of the Gaia-alerted eruptive young stars that has undergone several brightening events. We conducted monitoring observations using multi-filter optical and near-in…
Photometric and spectroscopic study of the burst-like brightening of two Gaia-alerted young stellar objects
Zsófia Nagy, Péter Ábrahám, Ágnes Kóspál +18
Young stars show variability on different time-scales from hours to decades, with a range of amplitudes. We studied two young stars, which triggered the Gaia Science Alerts system…
