Towards Galactic Archaeology with Inferred Ages of Giant Stars From Gaia Spectra
Aisha S. Almannaei, Daisuke Kawata, Ioana Ciuca +4
In the era of Gaia, the accurate determination of stellar ages is transforming Galactic archaeology. We demonstrate the feasibility of inferring stellar ages from Gaia's RVS spectr…
Mixed-mode coupling in the Red Clump I. Standard single star models
Walter E. van Rossem, Andrea Miglio, Josefina Montalbán
The investigation of global, resonant oscillation modes in red giant stars offers valuable insights into their internal structures. In this study, we investigate in detail the info…
Anomalously low-mass core-He-burning star in NGC 6819 as a post-common-envelope phase product
Massimiliano Matteuzzi, David Hendriks, Robert G. Izzard +5
Precise masses of red-giant stars enable a robust inference of their ages, but there are cases where these age estimates are highly precise yet very inaccurate. Examples are core-h…
The Wide-field Spectroscopic Telescope (WST) Science White Paper
Vincenzo Mainieri, Richard I. Anderson, Jarle Brinchmann +214
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial con…
Discovery of the local counterpart of disc galaxies at z > 4: The oldest thin disc of the Milky Way using Gaia-RVS
Samir Nepal, Cristina Chiappini, Anna B. A. Queiroz +5
JWST has recently detected numerous disc galaxies at high-redshifts and there have been observations of cold disc galaxies at z > 4 with ALMA. In the Milky Way, recent studies find…
Stellar population astrophysics (SPA) with the TNG. Abundance analysis of nearby red giants and red clump stars: combining high resolution spectroscopy and asteroseismology
Nagaraj Vernekar, Sara Lucatello, Angela Bragaglia +4
Context: Asteroseismology, a powerful approach for obtaining internal structure and stellar properties, requires surface temperature and chemical composition information to determi…
