Long-term optical and near-infrared photometric evolution of SN 2019vxm, an interacting Type IIn supernova

Klára Lelkes, László Molnár, József Vinkó +12

The diversity of Type IIn supernovae is largely driven by the properties of the circumstellar material (CSM) they explode into. We examine the temporal evolution of SN 2019vxm, an…

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…

Gaia20dsk: A new MNor discovered by the GLORIOUS collaboration

Patrik E. Németh, Fernando Cruz-Sáenz de Miera, Ágnes Kóspál +10

Context. Among known young stellar objects (YSOs), those exhibiting the most dramatic increases in brightness due to sudden increase in mass accretion rate are eruptive young stars…

The Outbursting YSOs Catalogue (OYCAT)

C. Contreras Peña, J. -E. Lee, G. Herczeg +39

YSOs can display unpredictable and high-amplitude rises in brightness that can last from a few months to possibly over 100 years. These types of outbursts are explained by large ch…

Short- and long-term variations of the high mass accretion rate classical T Tauri star DR Tau

Gabriella Zsidi, Ágnes Kóspál, Péter Ábrahám +20

Classical T Tauri stars are newly formed, low mass stars which may display both periodic and random variations in their brightness. The interaction between the star and its circums…

The 2023 outburst of the Gaia alerted EXor Gaia23bab

Zsófia Nagy, Ágnes Kóspál, Péter Ábrahám +33

Episodic accretion is a fundamental process in the build-up of the stellar mass. EX Lupi-type eruptive young stars (EXors) represent one of the main types of episodic accretion. We…
