Mass effect on the lithium abundance evolution of open clusters: Hyades, NGC 752, and M67

Matthieu Castro, Tharcísyo Duarte, Giancarlo Pace +1

Lithium abundances in open clusters provide an effective way of probing mixing processes in the interior of solar-type stars and convection is not the only mixing mechanism at work…

The Gaia-ESO Survey: Chromospheric Emission, Accretion Properties, and Rotation in Velorum and Chamaeleon I

A. Frasca, K. Biazzo, A. C. Lanzafame +33

We use the fundamental parameters delivered by the GES consortium in the first internal data release to select the members of Vel and Cha I among the UVES and GIRAFFE spectrosc…

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…
