Lacerta OB1协会
The Lacerta OB1 Association
摘要：
Lac OB1是一个邻近的OB星协，正处于恒星形成的最后阶段。虽然成员星表明膨胀的时间尺度为数千万年，但最新的恒星形成事件，如大质量和前主序星的存在所证明的那样，发生在几百万年前。该区域残留的分子云提供了大质量恒星引发恒星诞生的证据。
英文摘要：
Lac OB1 is a nearby OB association in its final stage of star formation. While the member stars suggest an expansion time scale of tens of Myr, the latest star formation episode, as manifested by the existence of massive and pre-main sequence stars, took place no more than a few Myr ago. The remnant molecular clouds in the region provide evidence of starbirth triggered by massive stars.
