Article aim is to study the chemical distribution of the Galactic disk using open clusters by analyzing the existence of gradients with Galactocentric distance, azimuth, or height from the plane and dependency with age.
12C/13C of Kepler giant stars: The missing piece of the mixing puzzle
N. Lagarde, R. Minkevičiūtė, A. Drazdauskas, G. Tautvaišienė, C. Charbonnel, C. Reylé, A. Miglio, T. Kushwahaa and B. Bale
Articles aims: We present the CNO and 12C/13C abundances derived for 71 giant field stars. Then, using this new catalogue and complementary data from the Kepler and Gaia satellites, we study the efficiency of mixing occurring in the giant branch as a function of the stellar properties of the stars (e.g. mass, age, metallicity).
The role of radial migration in open cluster and field star populations with Gaia DR3
C. Viscasillas Vázquez, L. Magrini, L. Spina, G. Tautvaišienė, M. Van der Swaelmen, S. Randich and G. G. Sacco
Aims. This study aims to investigate whether open clusters and field stars respond differently to the perturbations that cause radial migration. In particular, we aim to understand the nature of the oldest surviving clusters.
