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.

我们从超新星遗迹的B-V颜色(蓝色)、光度距离(位于超新星遗迹的距离)和自身运动(与遗迹中心的抛射不一致)中选择了超新星遗迹中潜在的O型和B型恒星。它们可能是在双星中以超新星形式抛出的逃逸恒星。我们想要拍摄这些恒星的低分辨率光谱，以确认它们是O型或B型恒星。如果得到证实，我们将在稍后测量它们的径向速度，以研究双星中抛射和超新星的运动学和动力学。在这个项目中，我们有一晚在卡拉阿尔托2.2米进行观测。
