仙后座的恒星形成区

Star Forming Regions in Cassiopeia

M. Kun

摘要:

本章描述了仙后座中的恒星形成区,银河系坐标范围为120度< l < 130度,-5度< b < +15度。在b > 10度时,附近的云L1333和L1340出现在这个区域。在仙后座的银河系本地臂只包含几个恒星形成区,比邻近的仙王座的OB星协更小,更不活跃。讨论了该系统的五个成员LkH α 198及其环境L1287、L1293、L1302 / NGC 255和S187。仙后座中几个更遥远的OB星协和巨星形成区与2.0-3.0 kpc的英仙座臂有关。其中,Herbig Be星MWC 1080是本章讨论的重点。

英文摘要:

This chapter describes the Galactic star forming regions in the constellation Cassiopeia, in the Galactic coordinate range 120 deg < l < 130 deg, -5 deg < b < +15 deg. At b > 10 deg the nearby clouds L1333 and L1340 are found in this region. The local arm of the Galaxy in Cassiopeia contains only a few star forming regions, smaller and less active than the OB associations of the neighboring Cepheus. Five members of this system, LkHalpha 198 and its environment, L1287, L1293, L1302 / NGC 255, and S187 are discussed. Several more distant OB associations and giant star forming regions in Cassiopeia are associated with the Perseus arm at 2.0-3.0 kpc. Among these, the Herbig Be star MWC 1080 is discussed in this chapter.
