Ledoux's convection criterion in evolution and asteroseismology of massive stars (2009)
Lebreton, Yveline, Montalban, Josefina, Godart, Melanie, Morel, Pierre, Noels, Arlette, Dupret, Marc-Antoine
Saio et al. (2006) have shown that the presence of an intermediate convective zone (ICZ) in post-main sequence models could prevent the propagation of g-modes in the radiative interior and hence...
Stellar ages from asteroseismology (2008)
Lebreton, Yveline, Montalban, Josefina
Asteroseismology provides powerful means to probe stellar interiors. The oscillations frequencies are closely related to stellar interior properties via the density and sound speed profiles. Since...
Thorough analysis of input physics in CESAM and CLES codes (2008)
Montalban, Josefina, Lebreton, Yveline, Miglio, Andrea, Scuflaire, Richard, Morel, Pierre, Noels, Arlette
This contribution is not about the quality of the agreement between stellar models computed by CESAM and CLES codes, but more interesting, on what ESTA-Task~1 run has taught us about these codes and...
Lebreton, Yveline, Montalban, Josefina, Christensen-Dalsgaard, Joergen, Roxburgh, Ian W., Weiss, Achim
We compare stellar models produced by different stellar evolution codes for the CoRoT/ESTA project, comparing their global quantities, their physical structure, and their oscillation properties. We...
Revised instability domains of SPB and beta Cephei stars (2007)
Miglio, Andrea, Montalban, Josefina, Dupret, Marc-Antoine
The excitation of pulsation modes in beta Cephei and Slowly Pulsating B stars is known to be very sensitive to opacity changes in the stellar interior where T~2 10^5 K. In this region differences in...
12 Bootis: a test bed for extra-mixing processes in stars (2007)
Miglio, Andrea, Montalban, Josefina, Maceroni, Carla
12 Bootis is a spectroscopic binary whose visual orbit has been resolved by interferometry. Though the physical parameters of the system have been determined with an excellent precision, the...
New light on the old problem of lithium pre--MS depletion: models with 2D RHD convection (2006)
Montalban, Josefina, D'Antona, Francesca
The Teff location of Pre-Main Sequence (PMS) evolutionary tracks depends on the treatment of over-adiabaticity. We present here the PMS evolutionary tracks computed by using the mixing length theory...
Evolution and seismology of alpha Centauri (2005)
Montalban, Josefina, Miglio, Andrea
Solar-like oscillations detected in both components of the binary system alpha Centauri provide strong constraints on the fundamental parameters of the stellar system. We model alpha Centauri by...
