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…
