The Gaia satellite: a tool for Emission Line Stars and Hot Stars
Christophe Martayan, Yves Fremat, Ronny Blomme +19
The Gaia satellite will be launched at the end of 2011. It will observe at least 1 billion stars, and among them several million emission line stars and hot stars. Gaia will provid…
Asiago eclipsing binaries program. II. V570 Per
P. M. Marrese, U. Munari, R. Sordo +3
The orbit and physical parameters of the double-lined eclipsing binary V570 Per, discovered by the Hipparcos satellite, are derived with formal errors better than 1% using high res…
Criteria for spectral classification of cool stars in the near-IR GAIA wavelength region
F. Boschi, U. Munari, R. Sordo +1
The far-red portion of the spectrum offers bright prospects for an accurate classification of cool stars, like the giant components of symbiotic stars. The 8480--8740 Ang region, f…
High resolution spectral survey of symbiotic stars in the near-IR over the GAIA wavelength range
Paola M. Marrese, Rosanna Sordo, Ulisse Munari
High resolution (R~20,000), high signal-to-noise (S/N~100) spectra were collected for ~40 symbiotic stars with the Asiago echelle spectrograph over the same 8480-8740 Ang wavelengt…
