黑洞阴影在SSD中的位置和形状

Shape and Position of a Black Hole Shadow in SSD

假设旋转的黑洞在标准吸积盘内,在吸积盘的内边界等于最后稳定轨道的情况下,画出黑洞阴影在吸积盘的图像.通过定性和定量分析黑洞的形状和位置,发现对于相同质量的黑洞,黑洞阴影的大小及形状与黑洞的自旋参量有关.旋转黑洞阴影的形状和位置与它的旋转轴是不对称的,通过研究旋转轴与黑洞阴影的位置关系来确定黑洞的质量中心的位置及黑洞的旋转参量.

A rotating black hole is supposed to lie in a standard accretion disk.Imaging of the black hole shadow in an accretion disk are drawn as accretion disk inner boundary is equal to the last stable orbit.With qualitative and quantitative analysis of shape and position of a black hole,it is found that the size and shape of a black hole shadow for black holes with same mass are relevant to black hole spin.Shape and position of a rotating black hole shadow are asymmetrical relative to its rotating axis.The center of mass and rotation parameters of a black hole are determinated with position between rotating axis and black hole shadow.
