Ariel stellar characterisation IV. Fundamental parameters of 18 hot stars in the Ariel mission candidate sample
H. Ramler, S. P. D. Borthakur, C. P. Folsom +16
The characterisation of exoplanetary systems depends on the accurate determination of host star parameters. The Ariel mission will probe the atmospheres of a statistically signific…
PENELLOPE: IX. Lithium, iron and barium elemental abundances in eight nearby young clusters
R. Carini, K. Biazzo, A. Frasca +19
We conducted a homogeneous chemical analysis of pre-main sequence stars with effective temperatures ranging from 3000 K to 5500 K in eight nearby star-forming regions…
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…
Protoplanetary discs around sun-like stars appear to live longer when the metallicity is low
Guido De Marchi, Giovanna Giardino, Katia Biazzo +17
Previous Hubble Space Telescope (HST) observations of the star-forming cluster NGC 346 in the Small Magellanic Cloud (SMC) had revealed a large population of pre-main sequence (PMS…
Young Stellar Objects in NGC 346: A JWST NIRCam/MIRI Imaging Survey
Nolan Habel, Conor Nally, Laura Lenkic +17
We present a JWST imaging survey with NIRCam and MIRI of NGC 346, the brightest star-forming region in the Small Magellanic Cloud (SMC). By combining aperture and point spread func…
Gaia23bab : a new EXor
T. Giannini, E. Schisano, P. Abraham +10
On March 6 2023, the Gaia telescope has alerted a 2-magnitude burst from Gaia23bab, a Young Stellar Object in the Galactic plane. We observed Gaia23bab with the Large Binocular Tel…
The He abundance in NGC 1850 A and B: are we observing the early stage of formation of multiple populations in a stellar cluster?
R. Carini, A. Sollima, E. Brocato +1
We present the result of a sample of B-stars in the Large Magellanic Cloud young double stellar cluster NGC 1850 A and NGC 1850 B, observed with the integral-field spectrograph at…
GIARPS High-resolution Observations of T Tauri stars (GHOST) V. New insights into disk winds from 3 km/s resolution observations
Brunella Nisini, Manuele Gangi, Teresa Giannini +6
This paper aims at revisit the physical and dynamical properties of the warm atomic gas in the inner disk region of classical T Tauri stars (CTTs) and relate them to the properties…
Discovery of dusty sub-solar mass young stellar objects in NGC 346 with JWST/NIRCam
Olivia C. Jones, Conor Nally, Nolan Habel +23
JWST observations of NGC 346, a star-forming region in the metal-poor Small Magellanic Cloud, reveal a substantial population of sub-solar mass young stellar objects (YSOs) with IR…
Pre-main Sequence stars in LH91
R. Carini, K. Biazzo, G. De Marchi +3
We study the accretion properties of pre-main sequence low-mass stars in the LH 91 association within the Large Magellanic Clouds. Using optical multiband photometry obtained with…
