Observational signatures for depletion in the Spite plateau: solving the cosmological Li discrepancy?
J. Melendez, L. Casagrande, I. Ramirez +2
We present Li abundances for 73 stars in the metallicity range -3.5 < [Fe/H] < -1.0 using improved IRFM temperatures (Casagrande et al. 2010) with precise E(B-V) values obtained mo…
The peculiar solar composition and its possible relation to planet formation
Jorge Melendez, Martin Asplund, Bengt Gustafsson +1
We have conducted a differential elemental abundance analysis of unprecedented accuracy (0.01 dex) of the Sun relative to 11 solar twins from the Hipparcos catalogue and 10 solar a…
An investigation of chromospheric activity spanning the Vaughan--Preston gap: impact on stellar ages
G. Pace, J. Melendez, L. Pasquini +5
Chromospheric activity is widely used as an age indicator for solar-type stars based on the early evidence that there is a smooth evolution from young and active to old and inactiv…
