Lithium abundance evolution in open clusters: Hyades, NGC752, and M67
Matthieu Castro, Giancarlo Pace, José Dias do Nascimento
Mixing mechanisms bring the Li from the base of the convective zone to deeper and warmer layers where it is destroyed. These mechanisms are investigated by comparing observations o…
The ionizing sources of luminous compact HII regions in the RCW106 and RCW122 clouds
J. M. C. Grave, M. S. N. Kumar, D. K. Ojha +2
Given the rarity of young O star candidates, compact HII regions embedded in dense molecular cores continue to serve as potential sites to peer into the details of high-mass star f…
Kinematics and chemical properties of the Galactic stellar populations. The HARPS FGK dwarfs sample
V. Zh. Adibekyan, P. Figueira, N. C. Santos +7
(Abridged) We analyze chemical and kinematical properties of about 850 FGK solar neighborhood long-lived dwarfs observed with the HARPS high-resolution spectrograph. The stars in t…
Chromospheric activity as age indicator
Giancarlo Pace
Chromospheric activity has been calibrated and widely used as an age indicator. However, it has been suggested that the viability of this age indicator is, in the best case, limite…
