Evaluating Gaia performances on eclipsing binaries. IV. Orbits and stellar parameters for SV Cam, BS Dra and HP Dra

E. F. Milone, U. Munari, P. M. Marrese +4

This is the fourth in a series of papers that aim both to provide reasonable orbits for a number of eclipsing binaries and to evaluate the expected performance of Gaia of these obj…

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…

Spectroscopic survey of the Galaxy with Gaia I. Design and performance of the Radial Velocity Spectrometer

D. Katz, U. Munari, M. Cropper +22

The definition and optimisation studies for the Gaia satellite spectrograph, the Radial Velocity Spectrometer (RVS), converged in late 2002 with the adoption of the instrument base…

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…

Asiago eclipsing binaries program. I. V432 Aur

A. Siviero, U. Munari, R. Sordo +4

The orbit and physical parameters of the previously unsolved eclipsing binary V432 Aur, discovered by Hipparcos, have been derived with errors better than 1% from extensive Echelle…

Lithium in the Symbiotic Mira V407 Cyg

A. A. Tatarnikova, P. M. Marrese, U. Munari +4

We report an identification of the lithium resonance doublet LiI 6708A in the spectrum of V407 Cyg, a symbiotic Mira with a pulsation period of about 745 days. The resolution of th…
