超铝X射线源及其星云

Ultraluminous X-ray Sources and Their Nebulae

Pavel Abolmasov

摘要:

超铝X射线源的一个有趣的特征是,它们中的许多都被表现出不同观测特性的发光星云所包围。在不同的情况下,星云是光致电离的或由冲击提供能量的。一般来说,这两种能源似乎是共存的。ULX气泡星云可能被认为是一种新的冲击动力星云,类似于放大版的恒星风气泡。它们的膨胀率支持恒定的能量流入,而不是像超新星爆炸这样的单一强大事件。

英文摘要:

One of the interesting features of Ultraluminous X-ray sources is that many of them are surrounded by luminous nebulae exhibiting diverse observational properties. In different cases the nebulae are photoionized or shock-powered. Generally, the two energy sources appear to coexist. ULX bubble nebulae may be considered a new class of shock-powered nebulae similar to upscaled versions of stellar wind bubbles. Their expansion rates support constant energy influx rather than single powerful events like Hypernova explosions.
