相对论厚吸积盘的铁谱线轮廓

Iron Line Profiles from Relativistic Thick Accretion Disk

Sheng-Miao Wu, Ting-Gui Wang

摘要:

本文提出了一种新的计算旋转黑洞周围有限厚度相对论吸积盘中Fe K α线轮廓的程序。随着吸积速率的增加,薄的开普勒吸积盘必然会变厚,并成为次开普勒。我们在这里开始,第一次,一个完全相对论性的计算,其目的是深入了解的几何厚度和次开普勒轨道速度的影响上的线轮廓。这个代码也很适合于产生吸积盘图像。

英文摘要:

We present a new code for calculating the Fe Kalpha line profiles from relativistic accretion disks with finite thickness around a rotating black hole. The thin Keplerian accretion disk must become thicker and sub-Keplerian with increasing accretion rates. We here embark on, for the first time, a fully relativistic computation which is aimed at gaining an insight into the effects of geometrical thickness and the sub-Keplerian orbital velocity on the line profiles. This code is also well-suited to produce accretion disk images.
