Recurrent strong outbursts of an EXor-like young eruptive star Gaia20eae
Fernando Cruz-Sáenz de Miera, Ágnes Kóspál, Péter Ábrahám +21
We present follow-up photometric and spectroscopic observations, and subsequent analysis of Gaia20eae. This source triggered photometric alerts during 2020 after showing a 3…
V899 Mon: a peculiar eruptive young star close to the end of its outburst
Sunkyung Park, Ágnes Kóspál, Fernando Cruz-Sáenz de Miera +15
V899 Mon is an eruptive young star showing characteristics of both FUors and EXors. It reached a peak brightness in 2010, then briefly faded in 2011, followed by a second outburst.…
A study of the photometric and spectroscopic variations of the prototypical FU Orionis-type star V1057 Cyg
Zs. M. Szabó, Á. Kóspál, P. Ábrahám +19
Among the low-mass pre-main sequence stars, a small group called FU Orionis-type objects (FUors) are notable for undergoing powerful accretion outbursts. V1057 Cyg, a classical exa…
Dipper-like variability of the Gaia alerted young star V555 Ori
Zsófia Nagy, Elza Szegedi-Elek, Péter Ábrahám +26
V555 Ori is a T Tauri star, whose 1.5 mag brightening was published as a Gaia science alert in 2017. We carried out optical and near-infrared photometric, and optical spectroscopic…
A new sample of warm extreme debris disks from the ALLWISE catalog
Attila Moór, Péter Ábrahám, Gyula Szabó +12
Extreme debris disks (EDDs) are rare systems with peculiarly large amounts of warm dust that may stem from recent giant impacts between planetary embryos during the final phases of…
