The Mass Accretion Rate and Stellar Properties in Class I Protostars
Eleonora Fiorellino, Lukasz Tychoniec, Fernando Cruz-Saenz de Miera +5
Stars collect most of their mass during the protostellar stage, yet the accretion luminosity and stellar parameters, which are needed to compute the mass accretion rate, are poorly…
Accretion process, magnetic fields, and apsidal motion in the pre-main sequence binary DQ Tau
Kim Pouilly, Oleg Kochukhov, Ágnes Kóspál +3
Classical T Tauri stars (CTTSs) are young stellar objects that accrete materials from their accretion disc influenced by their strong magnetic field. The magnetic pressure truncate…
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…
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…
The relation between the Mass Accretion Rate and the Disk Mass in Class I Protostars
Eleonora Fiorellino, Lukasz Tychoniec, Carlo F. Manara +5
The evidence of a relation between the mass accretion rate and the disk mass is established for young, Class II pre-main sequence stars. This observational result opened an avenue…
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…
