Theoretical predictions of surface light element abundances in protostellar and pre-Main Sequence phase
E. Tognelli, S. Degl'Innocenti, P. G. Prada Moroni +5
Theoretical prediction of surface stellar abundances of light elements -- lithium, beryllium, and boron -- represents one of the most interesting open problems in astrophysics. As…
The Gaia-ESO survey: Mixing processes in low-mass stars traced by lithium abundance in cluster and field stars
L. Magrini, N. Lagarde, C. Charbonnel +42
We aim to constrain the mixing processes in low-mass stars by investigating the behaviour of the Li surface abundance after the main sequence. We take advantage of the data from th…
On the Metamorphosis of the Bailey diagram for RR Lyrae stars
G. Bono, V. F. Braga, J. Crestani +37
We collected over 6000 high-resolution spectra of four dozen field RR Lyrae (RRL) variables pulsating either in the fundamental (39 RRab) or in the first overtone (9 RRc) mode. We…
Protostellar accretion in low mass metal poor stars and the cosmological lithium problem
E. Tognelli, P. G. Prada Moroni, S. Degl'Innocenti +2
The cosmological lithium problem, that is, the discrepancy between the lithium abundance predicted by the Big Bang nucleosynthesis and the one observed for the stars of the 'Spite…
Protostellar accretion and the cosmological lithium problem
S. Cassisi, M. Salaris, S. Degl'Innocenti +2
The cosmological lithium problem, i.e. the discrepancy between the lithium abundance predicted by the Big Bang Nucleosynthesis and the one observed for the stars of the "Spite plat…
Evidence of a substellar companion to AB Dor C
J. B. Climent, J. P. Berger, J. C. Guirado +5
Studies of fundamental parameters of very low-mass objects are indispensable to provide tests of stellar evolution models that are used to derive theoretical masses of brown dwarfs…
