恒星晕的逆康普顿辐射

Inverse-Compton emission from halos around stars

Elena Orlando, Andrew W. Strong

摘要:

相对论性电子的逆康普顿散射是银河系漫辐射的主要组成部分。涉及的光子场是宇宙微波背景和来自恒星和尘埃的星际辐射场。逆康普顿分布的计算通常假设一个平滑的ISRF,但事实上银河系的光度很大一部分来自最明亮的恒星,这是罕见的。因此,我们预计ISRF,从而逆康普顿发射,是cluquiles。我们还表明,一些最明亮的恒星可能是可见的玻璃。在本文中,我们给出了我们以前的工作,包括周围的恒星的强度分布的例子,和天鹅座OB2的预测光谱的更新。

英文摘要:

Inverse Compton scattering by relativistic electrons produces a major component of the diffuse emission from the Galaxy. The photon fields involved are the cosmic microwave background and the interstellar radiation field from stars and dust. Calculations of the inverse Compton distribution have usually assumed a smooth ISRF, but in fact a large part of the Galactic luminosity comes from the most luminous stars which are rare. Therefore we expect the ISRF, and hence the inverse Compton emission, to be clumpy. We also show that some of the most luminous stars may be visible to GLAST. In this paper we give an update on our previous work including examples of the intensity distribution around stars, and the predicted spectrum of Cygnus OB2.
