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…
Activity of TRAPPIST-1 analogue stars observed with TESS
Bálint Seli, Krisztián Vida, Attila Moór +2
As more exoplanets are being discovered around ultracool dwarfs, understanding their magnetic activity -- and the implications for habitability -- is of prime importance. To find s…
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…
Physical conditions of gas components in debris disks of 49 Ceti and HD 21997
Aya E. Higuchi, Ágnes Kóspál, Attila Moór +2
Characterization of gas component in debris disks is of fundamental importance for understanding its origin. Toward this goal, we have conducted non-LTE (local thermodynamic equili…
Gaia 18dvy: a new FUor in the Cygnus OB3 association
E. Szegedi-Elek, P. Ábrahám, L. Wyrzykowski +59
We present optical-infrared photometric and spectroscopic observations of Gaia18dvy, located in the Cygnus OB3 association at a distance of 1.88 kpc. The object was noted by the Ga…
