The Stellar Population of NGC 346 in the Small Magellanic Cloud with JWST

J. Jaspers, P. Kavanagh, G. De Marchi +13

NGC 346 is a massive star-forming region located at a distance of 62 kpc, in the Small Magellanic Cloud (SMC). Due to its low metallicity (Z 1/5 Z), it is an…

Bridging the UV Gap: The HST Ultraviolet Foundation for Star Formation Science in the Era of Roman, Euclid, and HWO

F. Z. Majidi, A. Bayo, K. Biazzo +4

As we enter the 2030s, the astronomical landscape will be dominated by large-scale infrared (IR) and optical surveys led by JWST, Euclid, and the Nancy Grace Roman Space Telescope.…

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…

The GAPS Programme at the TNG: LXX. TOI-5734b: A hot sub-Neptune orbiting a relatively young K dwarf with an Earth-like density

S. Filomeno, T. Trifonov, M. Damasso +40

Increasing interest in young exoplanets is leading to a growing effort to understand the formation and evolutionary processes responsible for their different architectures. One int…

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…
