Christopher W. Mauche, Duane A. Liedahl, Shizuka Akiyama, Tomasz Plewa

摘要:

我们描述了辐射驱动的光电离风和吸积流的高质量X射线双星船帆座X-1的全球模型的初步结果。完整的模型结合了FLASH流体动力学计算,XSTAR光电离计算,HULLAC原子数据,和蒙特卡罗辐射输运。我们目前的密度,温度,速度和电离参数的FLASH二维随时间变化的模拟船帆座X-1的地图,以及地图的X射线发射线的发射率分布。

英文摘要:

We describe preliminary results of a global model of the radiatively-driven photoionized wind and accretion flow of the high-mass X-ray binary Vela X-1. The full model combines FLASH hydrodynamic calculations, XSTAR photoionization calculations, HULLAC atomic data, and Monte Carlo radiation transport. We present maps of the density, temperature, velocity, and ionization parameter from a FLASH two-dimensional time-dependent simulation of Vela X-1, as well as maps of the emissivity distributions of the X-ray emission lines.
