Gaia20dsk: A new MNor discovered by the GLORIOUS collaboration
Patrik E. Németh, Fernando Cruz-Sáenz de Miera, Ãgnes 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…
Spectroscopic follow-up of Gaia alerted Young Stellar Object variables: the Large Binocular Telescope view
Teresa Giannini, Manuele Gangi, Fernando Cruz-Saenz de Miera +13
We analyzed optical/near-IR Large Binocular Telescope spectra of 16 sources alerted by Gaia between 2021 and 2024 due to significant photometric variability. Half of the spectra we…
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…
A Multi-wavelength, Multi-epoch Monitoring Campaign of Accretion Variability in T Tauri Stars from the ODYSSEUS Survey. III. Optical Spectra
John Wendeborn, Catherine C. Espaillat, Thanawuth Thanathibodee +20
Classical T Tauri Stars (CTTSs) are highly variable stars that possess gas- and dust-rich disks from which planets form. Much of their variability is driven by mass accretion from…
A Multi-wavelength, Multi-epoch Monitoring Campaign of Accretion Variability in T Tauri Stars from the ODYSSEUS Survey. I. HST FUV and NUV Spectra
John Wendeborn, Catherine C. Espaillat, Sophia Lopez +17
The Classical T Tauri Star (CTTS) stage is a critical phase of the star and planet formation process. In an effort to better understand the mass accretion process, which can dictat…
The Enigma of Gaia18cjb: a Rare Hybrid of FUor and EXor?
Eleonora Fiorellino, Peter Abraham, Agnes Kospal +28
Context. Gaia18cjb is one of the Gaia-alerted eruptive young star candidates which has been experiencing a slow and strong brightening during the last 13 years, similar to some FU…
