A More Complex Than Expected Formation History of the Milky Way's Last Major Merger
Hai-Feng Wang, Guan-Yu Wang, Giovanni Carraro +3
The GaiaSausageEnceladus (GSE) structure, widely recognized as the most recent major accretion event experienced by our Galaxy, is traditionally interpreted as the remnant of…
A method to derive self-consistent NLTE astrophysical parameters for 4 million high-resolution 4MOST stellar spectra in half a day with invertible neural networks
Victor F. Ksoll, Nicholas Storm, Maria Bergemann +5
Modern spectroscopic surveys obtain spectra for millions of stars. However, classical spectroscopic methods can often be computationally expensive, rendering them impractical for t…
Mapping the Ages of Stars with Chemistry
Carlos Viscasillas Vázquez, Giada Casali, Laura Magrini +11
Chemical clocks, based on age-sensitive stellar abundance ratios, offer a powerful and scalable approach to reconstruct the formation history of the Milky Way. This white paper out…
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-…
