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…
Transients as Determinants of Habitability
Fatemeh Zahra Majidi, Katia Biazzo, Maria Tsantaki +7
Stellar magnetic activity, manifested through spots (faculae and flares), fundamentally shapes the exoplanets' environments. For low-mass stars in particular, where most habitable-…
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…
The 2023 outburst of the Gaia alerted EXor Gaia23bab
Zsófia Nagy, Ãgnes Kóspál, Péter Ãbrahám +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…
