反馈过程：理论观点
Feedback Processes [in Massive Star Formation]: A Theoretical Perspective
摘要：
我审查的证据的重要性，从大质量的恒星在小尺度和大尺度的反馈。反馈机制包括吸积光度、电离辐射、准直外流和恒星风。好消息是反馈并不能完全阻止大质量恒星的形成，而坏消息是我们不知道是什么限制了它们的质量。来自大质量恒星的反馈也会影响它们的周围环境。我认为，这不会产生一个以上的触发效率统一，也不会阻止大量的快速恒星形成的GMCs，虽然它可能会保留大量的残留物的云许多动态的时间。
英文摘要：
I review the evidence for the importance of feedback from massive stars at small and large scales. The feedback mechanisms include accretion luminosity, ionizing radiation, collimated outflows, and stellar winds. The good news is that feedback doesn't entirely prevent the formation of massive stars, while the bad news is that we don't know what does limit their masses. Feedback from massive stars also influences their surroundings. I argue that this does not produce a triggering efficiency above unity, nor does it prevent lots of prompt star formation in GMCs, though it may preserve massive remnants of the clouds for many dynamical times.
