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…
Discovery of Volatile Gas in the Giant Impact Disk around the 150-Myr old HD 23514
Kate Y. L. Su, Attila Moór, Chengyan Xie +8
We report the discovery of CO gas emission around HD 23514, an F5V star in the 150 Myr-old Pleiades cluster, hosting one of the rare giant-impact disks with unique minera…
JWST's sharper view of EX Lup: cold water from ice sublimation during accretion outbursts
Sarah A. Smith, Carlos E. Romero-Mirza, Andrea Banzatti +9
The unstable accretion phases during pre-main-sequence evolution of T Tauri stars produce variable irradiation and heating of planet-forming regions. A strong accretion outburst wa…
