LS 5039中的TeV发射极结构
The TeV emitter structure in LS 5039
摘要：
LS 5039是一颗X射线双星，在极高能量下被发现。沿着轨道，有一个显着的检测，即使在优越的结合紧凑的对象，当非常大的伽马射线不透明度是预期的。电磁级联，这可能使系统更透明的伽马射线，几乎没有效率的合理磁场在大质量的恒星周围。类似射流的流动可以将能量传输到光子-光子吸收低得多的区域，并且TeV辐射不会被严重吸收。否则，在LS 5039的标准脉冲星场景中，发射器将位于恒星和紧凑物体之间，这意味着违反了X射线的观测限制。
英文摘要：
LS 5039 is an X-ray binary detected at very high energies. Along the orbit, there is a significant detection even during the superior conjunction of the compact object, when very large gamma-ray opacities are expected. Electromagnetic cascades, which may make the system more transparent to gamma-rays, are hardly efficient for reasonable magnetic fields in the massive star surroundings. A jet-like flow could transport energy to regions where the photon-photon absorption is much lower and the TeV radiation is not so severely absorbed. Otherwise, in the standard pulsar scenario for LS 5039, the emitter would be located between the star and the compact object, which would imply the violation of the observational constraints at X-rays.
