Abstract

As part of our project for studying bright (V < 10 mag) eclipsing binaries discovered using images from the NASA STEREO mission we are accumulating follow-up observations with the goal of complete characterization of the systems. The full complement of data consist of light curves extracted from STEREO photometry, wide coverage Echelle spectra obtained at Apache Point Observatory for stellar characterization and Coude spectra obtained at NAO Rozhen for radial velocity curves. Here we present physical parameters-masses and radii- for six short period (P < 3 d) single line binary systems containing low-mass components.
