Disentangling discrepancies between stellar evolution theory and sub-solar mass stars. The influence of the mixing length parameter for the UV Psc binary
E. Lastennet, J. Fernandes, D. Valls-Gabaud +1
Serious discrepancies have recently been observed between predictions of stellar evolution models in the 0.7-1.1 M_sun mass range and accurately measured properties of binary stars…
Detached double-lined eclipsing binaries as critical tests of stellar evolution : Age and metallicity determinations from the HR diagram
E. Lastennet, D. Valls-Gabaud
Detached, double-lined spectroscopic binaries which are also eclipsing provide the most accurate determinations of stellar mass, radius, temperature and distance-independent lumino…
A Candidate M31/M32 Intergalactic Microlensing Event
S. Paulin-Henriksson, P. Baillon, A. Bouquet +13
We report the discovery of a microlensing candidate projected 2'54" from the center of M32, on the side closest to M31. The blue color (R-I= 0.00 +/- 0.14) of the source argues str…
A revised HRD for individual components of binary systems from BaSeL BVRI synthetic photometry. Influence of interstellar extinction and stellar rotation
E. Lastennet, J. Fernandes, Th. Lejeune
Johnson BVRI photometric data for individual components of binary systems have been provided by ten Brummelaar et al. (2000). This is essential because such binaries could play a c…
BaSeL: a library of synthetic spectra and colours for GAIA
E. Lastennet, T. Lejeune, E. Oblak +2
The BaseL Stellar Library (BaSeL) is a library of synthetic spectra which has already been used in various astrophysical applications (stellar clusters studies, characterization an…
Significant discrepancies between stellar evolution models and solar-type eclipsing and visual binaries ?
E. Lastennet, J. Fernandes, E. Oblak +1
Individual components of well-detached binary systems are assumed to be two single-like stars with a common origin, i.e. they share the same chemical composition and same age. Ther…
