SpaceInn Work Package 3.3 Accompanying report on the deliverables D3.8 due for April 30: reduced HARPS spectra with indicators

Abstract

In the framework of the SpaceInn project, the ground-based CoRoT complementary archive (Work Package 3.3) will contain 7103 spectra of the 261 stars observed with the HARPS spectrograph, mostly as complementary observations to the photometric light curves of many of the asteroseismological targets of the CoRoT satellite. A certain number of the archived spectra pertain to other, non-CoRoT targets: these objects were observed in order to better characterize the variability classes of the CoRoT targets. Our tasks until now have been the following: • the spectra have been reduced, normalized, and converted in VO-compliant fits files; • the mean line profile has been computed for each spectrum; • the radial velocity, vsin i, a binarity flag, a CaHK activity index, and an Hα emission index have been computed for each spectrum. In the case of double or multiple systems, the radial velocities and vsin i have been computed, if possible, for all the components; • the physical parameters Teff , log g, and [Fe/H] have been computed for each target.
