Mid-infrared time-domain study of recent dust production events in the extreme debris disc of TYC 4209-1322-1
A. Moór, P. Ábrahám, Á. Kóspál +23
Extreme debris discs are characterized by unusually strong mid-infrared excess emission, which often proves to be variable. The warm dust in these discs is of transient nature and…
Accretion and extinction variations in the low-mass pre-main sequence binary system WX Cha
Eleonora Fiorellino, Gabriella Zsidi, Agnes Kospal +5
Light curves of young star systems show photometric variability due to different kinematic, and physical processes. One of the main contributors to the photometric variability is t…
Grain growth in newly discovered young eruptive stars
Á. Kóspál, P. Ábrahám, A. Carmona +4
FU Orionis-type stars are young stellar objects showing large outbursts due to highly enhanced accretion from the circumstellar disk onto the protostar. FUor-type outbursts happen…
Identification of Young Stellar Object candidates in the DR2 x AllWISE catalogue with machine learning methods
G. Marton, P. Ábrahám, E. Szegedi-Elek +8
The second Data Release (DR2) contains astrometric and photometric data for more than 1.6 billion objects with mean magnitude 20.7, including many Young Stella…
Dust evolution in the circumstellar disc of the unclassified B[e] star HD 50138
J. Varga, T. Gerják, P. Ábrahám +3
We studied the disc of the unclassified B[e] star HD 50138, in order to explore its structure, and to find indications for the evolutionary status of this system, whether it is a y…
The outbursting protostar 2MASS~22352345+7517076 and its environment
Maria Kun, Peter Abraham, Jose Antonio Acosta Pulido +2
We studied the Class I protostar 2MASS 22352345+7517076 whose dramatic brightening between the IRAS, Akari, and WISE surveys was reported by Onozato et al. (2015). 2MASS 22352345+7…
