We created a large database of physical parameters and variability indicatorsby fully reducing and analysing the large number of spectra taken to complementthe asteroseismic observations of the CoRoT satellite. 7103 spectra of 261stars obtained with the ESO echelle spectrograph HARPS have been stored in theVO-compliant database Spectroscopic Indicators in a SeisMic Archive (SISMA),along with the CoRoT photometric data of the 72 CoRoT asteroseismic targets.The remaining stars belong to the same variable classes of the CoRoT targetsand were observed to better characterize the properties of such classes.Several useful variability indicators (mean line profiles; indices ofdifferential rotation, activity and emission lines) together with vsini andradial velocity measurements have been extracted from the spectra. Theatmospheric parameters Teff, logg and [Fe/H] have been computed following ahomogeneous procedure. As a result, we fully characterize a sample of new andknown variable stars by computing several spectroscopic indicators, alsoproviding some cases of simultaneous photometry and spectroscopy.
