LBT-MODS spectroscopy of young stellar objects in the distant metal-poor star forming region Sh2-284: Stellar and accretion properties
Katia Biazzo, Juan Manuel Alcalá, Felice Cusano +9
We present a spectroscopic survey of young stellar objects (YSOs) in Sh2-284, a distant (~4.5 kpc), low-metallicity (Z~1/3 Zsun) star-forming region (SFR) toward the Galactic antic…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
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…
JOYS: Launching and destruction of dust in protostellar jets. The case of BHR71-IRS1 with JWST/MIRI
Åukasz Tychoniec, Logan Francis, Maria Gabriela Navarro +24
Protostellar winds can theoretically lift solids from the planet-forming disks, but direct evidence for launched dust has been scarce so far. Numerous atomic lines that are unique…
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…
PROJECT-J: the shocking H2 outflow from HH46
Maria Gabriela Navarro, Brunella Nisini, Teresa Giannini +14
We analyze the H2 emission observed in the HH46 Class I system as part of PROJECT-J (Protostellar Jets Cradle Tested with JWST), to investigate the origin and excitation of the war…
