Grid-based estimates of stellar ages in binary systems. SCEPtER: Stellar CharactEristics Pisa Estimation gRid

G. Valle, M. Dell'Omodarme, P. G. Prada Moroni +1

We investigate the performance of grid-based techniques in estimating the age of stars in detached eclipsing binary systems. We evaluate the precision of the estimates due to the u…

Evolutionary stellar population synthesis with MILES - II. Scaled-solar and α-enhanced models

A. Vazdekis, P. Coelho, S. Cassisi +6

We present models that predict spectra of old- and intermediate-aged stellar populations at 2.51Å (FWHM) with varying [α/Fe] abundance. The models are based on the MILES library an…

Oxygen isotopic ratios in intermediate-mass red giants

Thomas Lebzelter, Oscar Straniero, Kenneth Hinkle +2

Context. The abundances of the three main isotopes of oxygen are altered in the course of the CNO-cycle. When the first dredge-up mixes the burning products to the surface, the nuc…

Multiple stellar populations in Magellanic Cloud clusters. III. The first evidence of an extended main sequence turn-off in a young cluster: NGC1856

A. P. Milone, L. R. Bedin, G. Piotto +7

Recent studies have shown that the extended main-sequence turn off (eMSTO) is a common feature of intermediate-age star clusters in the Magellanic Clouds (MCs). The most simple exp…

Stellar models with mixing length and T(tau) relations calibrated on 3D convection simulations

Maurizio Salaris, Santi Cassisi

(abridged) The calculation of the thermal stratification in the superadiabatic layers of stellar models with convective envelopes is a long standing problem of stellar astrophysics…

On the age of Galactic bulge microlensed dwarf and subgiant stars

G. Valle, M. Dell'Omodarme, P. G. Prada Moroni +1

Recent results by Bensby and collaborators on the ages of microlensed stars in the Galactic bulge have challenged the picture of an exclusively old stellar population. However, the…
