Gaia21bja: pre-main sequence star with quasi-periodic bursts
Ádám Mátéfy, Zsófia Nagy, Ágnes Kóspál +12
Gaia21bja is a Gaia alerted young stellar object (YSO) that exhibits at least seven quasi-peridoic brightenings over a 20 year-long light curve with durations of 1.5-2 years and am…
JWST/MIRI Spectroscopy of the Disk of the Young Eruptive Star EX Lup in Quiescence
Ágnes Kóspál, Péter Ábrahám, Lindsey Diehl +7
EX Lup is a low-mass pre-main sequence star that occasionally shows accretion-related outbursts. Here, we present JWST/MIRI medium resolution spectroscopy obtained for EX Lup fourt…
An APEX study of molecular outflows in FUor-type stars
Fernando Cruz-Sáenz de Miera, Ágnes Kóspál, Péter Ábrahám +4
FU Orionis-type objects (FUors) are low-mass pre-main-sequence objects which go through a short-lived phase (~100 years) of increased mass accretion rate (from 10^-8 to 10^-4 M_sun…
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…
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…
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…
