[40.05] Search for the Companions of Galactic SNe Ia

P. Ruiz-Lapuente (U. Barcelona)

The central regions of the remnants of Galactic SNe Ia have been examined for the presence of companion stars of the exploded supernovae. We present the results of this survey for the historical SN 1572 and SN 1006. The spectra of the stars are modeled to obtain Teff, log g and the metallicity. Radial velocities are obtained with an accuracy of 5--10 km s^-1. Implications for the nature of the companion star in SNeIa follow.
