Bayesian calibration of the mixing length parameter and of the helium-to-metal enrichment ratio with open clusters: the Hyades test-bed
E. Tognelli, M. Dell'Omodarme, G. Valle +2
We tested the capability of a Bayesian procedure to calibrate both the helium abundance and the mixing length parameter (), using precise photometric data for main-sequence…
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 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…
Relevance of the small frequency separation for asteroseismic stellar age, mass, and radius. A statistical investigation for main-sequence low-mass stars
G. Valle, M. Dell'Omodarme, P. G. Prada Moroni +1
We performed a theoretical analysis on the relevance of the small frequency separation in determining stellar ages, masses, and radii. We adopted the SCEPtER pipeline for low-…
