LS 5039星风结构的研究

Studying the Structure of the Stellar Wind in LS 5039

V. Bosch-Ramon

摘要:

双星LS 5039是一个非热X射线发射体,具有类似喷流的射电结构,也是银河系中最神秘的TeV源之一。LS 5039中O型星的存在意味着非热辐射源必须嵌入强烈的恒星风中,后者的作用可能与理解源的高能行为有关。在这项工作中,我们表明,LS 5039的软X射线光谱中缺乏吸收功能,可以强烈地限制描述风的参数,并最终限制非热发射体的位置。

英文摘要:

The binary LS 5039 is a non-thermal X-ray emitter that presents jet-like radio structures, and is also one of the most misterious TeV sources in our Galaxy. The presence of an O-type star in LS 5039 implies that the non-thermal emitter must be embedded in a strong stellar wind, and the role of the latter could be relevant for the understanding of the high-energy behavior of the source. In this work, we show that the lack of absorption features in the soft X-ray spectrum of LS 5039 can constrain strongly the parameters that describe the wind, and ultimately the location of the non-thermal emitter.
