Gaia21bja: pre-main sequence star with quasi-periodic bursts
Ãdám Mátéfy, Zsófia Nagy, Ãgnes 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…
The Accretion Process on Protostars
Eleonora Fiorellino, Alice Somigliana
The process of mass accretion onto Young Stellar Objects (YSOs) plays a fundamental role in determining the final stellar mass and setting the initial conditions for planet formati…
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…
Toward the time-domain spectroscopic study of the dynamic life of stars: from accretion to magnetic activity
Fatemeh Zahra Majidi, Amelia Bayo, Marc Audard +11
Stars and planets can be seen as the second fundamental building blocks of baryons in the universe (only second to the dust and gas in molecular clouds). Their formation involves d…
Coordinated Space- and Ground-based Monitoring of Accretion Bursts in a Protoplanetary Disk: The Orbital and Accretion Properties of DQ Tau
Hala Alqubelat, Carlo F. Manara, Justyn Campbell-White +9
Multiplicity in pre-main-sequence (PMS) systems shapes circumstellar and circumbinary disks, often producing features such as inner cavities, spiral arms, and gas streamers that fa…
