We have selected potential O- and B-type stars within supernova remnants from their B-V color (to be blue), their photometric distance (to lie at the distance of the supernova remnant), and from their proper motions(being not inconsistent with ejection from the remnants center).They could be runaway stars ejected in supernovae in binaries. We would like to take low-resolution spectra of thosestars in order to confirm them as O- or B-type stars. If confirmed, we would later measure their radial velocitiesto study the kinematics and dynamics of ejections and supernovae in binaries.We got one night at Calar Alto 2.2m to observe in this Project.
