Spectroscopic Indicators in a SeisMic Archive

SHORT DESCRIPTION and ROLE OF THE OBSERVATORY

INAF-OAB has a long tradition and experience in the study of variable stars and in asteroseismology (the study of the pulsation and oscillation modes of stars).
Stellar variability, whether due to activity, pulsations or otherwise, is a very effective tool for better understanding the structure of stars.
For this purpose, SISMA was created, an archive of spectroscopic data of 261 variable stars observed with the high-resolution echelle spectrograph HARPS – installed on the 3.6-metre diameter ESO telescope at the La Silla Observatory in Chile – to complement the work of the photometric satellite CoRoT (COnvection, ROtation and planetary Transits).

In fact, 71 of the SISMA stars are CoRoT targets observed simultaneously with the satellite, while the others belong to the same variability classes and help characterize these objects.
SISMA contains more than 7000 reduced spectra, stellar parameters, line profiles, activity and variability indicators and much more for all 261 observed stars.
Furthermore, the CoRot light curves for the stars in common with the satellite have also been included in the archive.
SISMA was created within the European program SpaceInn, which aimed to facilitate access to and exploitation of helium and asteroseismological data collected from the ground and from space.
