来自恒星形成区的伽马射线

Gamma rays from star-forming regions

Gustavo E. Romero

摘要:

自COS B卫星早期以来,恒星形成区一直与伽马射线源有关。在康普顿伽马射线天文台之后,这种关联的统计证据已经变得压倒性。切伦科夫望远镜的最新结果表明,一些高能量源产生于活跃的恒星形成区域,如天鹅座OB2和韦斯特伦德2。在本文中,我将简要回顾什么样的恒星物体可以在恒星形成区产生伽马射线辐射,我将建议,大质量恒星的形成过程中,原则上可以导致可观测到的伽马射线的生产。

英文摘要:

Star-forming regions have been tentatively associated with gamma-ray sources since the early days of the COS B satellite. After the Compton Gamma-Ray Observatory, the statistical evidence for such an association has became overwhelming. Recent results from Cherenkov telescopes indicate that some high-energy sources are produced in regions of active star formation like Cygnus OB2 and Westerlund 2. In this paper I will briefly review what kind of stellar objects can produce gamma-ray emission in star-forming regions and I will suggest that the formation process of massive stars could in principle result in the production of observable gamma rays.
