Evaluating GAIA performances on eclipsing binaries
Evaluating GAIA performances on eclipsing binaries
The orbits and physical parameters of three close, double-lined G0 eclipsing binaries have been derived combining photometry from the Hipparcos/Tycho mission with 8480–8740 Å ground-based spectroscopy. The setup is mimicking the photometric and spectroscopic observations that should be obtained by GAIA. The binaries considered here are all of G0 spectral …
