Camelopardalis中的年轻恒星和云

Young stars and clouds in Camelopardalis

V. Straizys, V. Laugalys

摘要:

本文评述了银河系黄道132- 158度方向上本旋臂中的恒星形成。在这个银河系方向最近的恒星形成活动的证据是这里的凸轮OB 1协会和密集的尘埃和分子云包含H $α$发射星,年轻的不规则变星和红外恒星物体的存在。本地臂的云集中在两层,分别在150-300 pc和大约900 pc处。在这个方向上的英仙座臂物体的距离约为2千秒差距。

英文摘要:

Star formation in the Local spiral arm in the direction of the Galactic longitudes 132--158 deg is reviewed. Recent star-forming activity in this Milky Way direction is evidenced by the presence here of the Cam OB1 association and dense dust and molecular clouds containing H$α$ emission stars, young irregular variables and infrared stellar objects. The clouds of the Local arm concentrate in two layers at 150-300 pc and at about 900 pc from the Sun. The Perseus arm objects in this direction are at a distance of about 2 kpc.
