A theoretical study to construct a unified model for high mass binaries with very high energy Gamma-ray emissions.

本研究的目的之一是建立一个统一的高质量双星的发射机制，发射非常高的能量γ射线的模型。对于包括脉冲星和Be型星星在内的高质量双星，我们采用数值模拟（1）和解析方法（2）研究了脉冲星风与星风/减速盘的相互作用.因此，我们表明，强烈的伽马射线从腔中发射，因为在腔中的高压和大的发射面积。在（2）的情况下，对于强驱动脉冲星，它进入盘的内部。从而解释了观测中γ射线的双峰光变曲线。

A goal of this study is to construct a unified model for an emission mechanism of high mass binaries emitting very high energy Gamma-rays. For high mass binaries including pulsar and Be type star, we research on interactions between pulsar wind and stellar wind/decretion disk using a numerical simulation (1) and an analytical approach (2).In the case of (1), for the high density disk a cavity is made in the disk by pulsar wind. Thus, we show that intense Gamma-rays are emitted from the cavity because of high pressure in the cavity and large emission area. In the case of (2), for the strongly driven pulsar it goes into more inside the disk. Thus, we show that a double-peak light curve of Gamma-rays in the observation is explained.
