Theoretical values of convective turnover times and Rossby numbers for solar-like, pre-main sequence stars
N. R. Landin, L. T. S. Mendes, L. P. R. Vaz
Magnetic fields are at the heart of the observed stellar activity in late-type stars, and they are presumably generated by a dynamo mechanism at the interface layer between the rad…
Combined effects of tidal and rotational distortions on the equilibrium configuration of low-mass, pre-main sequence stars
N. R. Landin, L. T. S. Mendes, L. P. R. Vaz
In close binary systems, rotation and tidal forces of the component stars deform each other and destroy their spherical symmetry. We present new models for low-mass, pre-main seque…
The triple system HIP96515: a low-mass eclipsing binary with a DB white dwarf companion
N. Huelamo, L. P. R. Vaz, C. A. O. Torres +8
HIP96515A is a double-lined spectroscopic binary with a visual companion (HIP96515B) at 8.6 arcsec. It is included in the SACY catalog as a potential young star and classified as a…
Four-colour photometry of eclipsing binaries. XLI uvby light curves for AD Bootis, HW Canis Majoris, SW Canis Majoris, V636 Centauri, VZ Hydrae, and WZ Ophiuchi
J. V. Clausen, L. P. R. Vaz, J. M. Garcia +4
CONTEXT: Accurate mass, radius, and abundance determinations from binaries provide important information on stellar evolution, fundamental to central fields in modern astrophysics…
