Oxygen isotopic ratio in open cluster RGB stars: A new method for accurate mass and age estimations
O. Straniero, C. Abia, I. Domínguez +1
Determining precise and homogeneous absolute ages of open clusters (OCs) remains a challenge in stellar astrophysics, mainly due to parameter degeneracies in photometric methods an…
Solar twins in Gaia DR3 GSP-Spec II. Age distribution and its implications for the Sun's migration
Takuji Tsujimoto, Daisuke Taniguchi, Alejandra Recio-Blanco +2
Solar twins are among the most powerful tracers of Galactic disk evolution owing to their unique property of sharing nearly solar metallicities ([Fe/H] ~ 0) while spanning a wide r…
Solar twins in Gaia DR3 GSP-Spec I. Building a large catalog of Solar twins with ages
Daisuke Taniguchi, Patrick de Laverny, Alejandra Recio-Blanco +2
[Abbreviated] Context. Solar twins, stars whose stellar parameters (Teff, log g, and [M/H]) are very close to the Solar ones, offer a unique opportunity to investigate Galactic arc…
