TOPoS VII. Age-metallicity relation in the Galactic halo and assembly of the Milky Way
P. Bonifacio, Y. Lebreton, I. Koutsouridou +8
One technique for determining stellar ages is to compare the position of a star in the Hertzsprung-Russell diagram to theoretical stellar evolutionary tracks. The sub-giant evoluti…
Stellar age determination using deep neural networks: Isochrone ages for 1.3 million stars, based on BaSTI, MIST, PARSEC, Dartmouth and SYCLIST evolutionary grids
T. Boin, L. Casamiquela, M. Haywood +4
We aim to develop a model-driven deep learning approach to age determination, by training neural networks on stellar evolutionary grids. Contrary to the usual data-driven deep lear…
Cesam2k20: A code for a new generation of stellar evolution models. I. Description of the code
L. Manchon, M. Deal, J. P. C. Marques +1
We present Cesam2k20, the latest version of the hydrostatic stellar evolution code CESAM originally developed by P. Morel and collaborators. Over the last three decades, it has und…
Physical interpretation of the oscillation spectrum on the RGB and AGB
G. Dréau, Y. Lebreton, B. Mosser +1
The high-frequency resolution of the four-year time series allows detailed study of seismic modes in luminous giants. Seismic observables help infer interior stru…
New stellar age estimates using SPInS based on Gaia DR3 photometry and LAMOST DR8 abundances
L. Casamiquela, D. R. Reese, Y. Lebreton +8
Reliable stellar age estimates are fundamental for testing several problems in modern astrophysics, in particular since they set the time scales of Galactic dynamical and chemical…
