A chromosome map to unveil stellar populations with different magnesium abundances. The case of Omega Centauri
A. P. Milone, A. F. Marino, A. Renzini +7
Historically, photometry has been largely used to identify stellar populations (MPs) in Globular Clusters (GCs) by using diagrams that are based on colours and magnitudes that are…
Li abundances for solar twins in the open cluster M67
Marilia Carlos, Jorge Melendez, Jose-Dias do Nascimento +1
We determine lithium (Li) abundances for solar twins in the M67 open cluster to add valuable information about the correlation between Li depletion and stellar age and, then, bette…
The effect of stellar activity on the spectroscopic stellar parameters of the young solar twin HIP 36515
Jhon Yana Galarza, Jorge Meléndez, Diego Lorenzo-Oliveira +7
Spectroscopic equilibrium allows us to obtain precise stellar parameters in Sun-like stars. It relies on the assumption of the iron excitation and ionization equilibrium. However,…
The Li-age correlation: the Sun is unusually Li deficient for its age
M. Carlos, J. Melendez, L. Spina +8
The present work aims to examine in detail the depletion of lithium in solar twins to better constrain stellar evolution models and investigate its possible connection with exoplan…
