密接联星密接联星是天文学中伴星与主星非常接近,共享一个互相接触或合并的气体包层的联星系统。共享包层的联星系统也称为overcontact或共享包层联星。 几乎所有已知的密接联星都是食联星,这类食密接联星称为大熊座W变星,其原型为大熊座W 。 密接联星经常会与共包层星混淆。然而,前者是在其数百万至数十亿年的一生中,有令人动容的稳定组态的两颗联星;后者描述的是联星发展在恒星动力学不稳定的阶段,不是驱散就是共享恒星包层,而在时间尺度上只有几个月到数年。

Contact binary 密接联星In astronomy, a contact binary is a binary star system whose component stars are so close that they touch each other or have merged to share their gaseous envelopes. A binary system whose stars share an envelope may also be called an overcontact binary. Almost all known contact binary systems are eclipsing binaries; eclipsing contact binaries are known as W Ursae Majoris variables, after their type star, W Ursae Majoris. |
