Evaluating GAIA performances on eclipsing binaries. III. Orbits and stellar parameters for UW LMi, V432 Aur and CN Lyn
P. M. Marrese, U. Munari, A. Siviero +5
The orbits and physical parameters of three detached F and G-type eclipsing binaries have been derived combining Hipparcos H(P) photometry with 8480-8740 Ang ground-based spectrosc…
Observational Studies of Early-type Overcontact Binaries: TU Muscae
Dirk Terrell, Ulisse Munari, Tomaz Zwitter +1
We present new spectroscopic and photometric data on the early-type overcontact binary TU Muscae. The analysis of the spectroscopic data shows that the line of sight to the system…
Spectroscopy, Photometry and Micro-arcsec Astrometry of Binaries with the GAIA Space Mission and with the RAVE Experiment
Tomaz Zwitter, Ulisse Munari
GAIA astrometric mission of ESA will be very efficient in discovering binary and multiple stars with any orbital period, from minutes to millions of years. Main parameters of the r…
Evaluating GAIA performances on eclipsing binaries. II. Orbits and stellar parameters for V781 Tau, UV Leo and GK Dra
T. Zwitter, U. Munari, P. M. Marrese +5
The orbits and physical parameters of three close, double-lined G0 eclipsing binaries have been derived combining H_P, V_T, B_T photometry from the Hipparcos/Tycho mission with 848…
Observational tests of the GAIA expected harvest on eclipsing binaries
Tomaz Zwitter
GAIA observations of eclipsing binary stars will have a large impact on stellar astrophysics. Accurate parameters, including absolute masses and sizes will be derived for $\sim 10^…
Grids of synthetic spectra for the GAIA mission
Tomaz Zwitter, Ulisse Munari, Fiorella Castelli
Two sets of grids of Kurucz ATLAS~9 model spectra are presented. The first one covers the GAIA spectral interval, while the second one which is still being computed covers the whol…
