黑洞发光环谱线轮廓的精确解

Precise Solution of Line Profiles for a Black Hole with a Luminous Ring in Its Accretion Disk

围绕黑洞作开普勒运动的环状发光物所发射的光，将受到多普勒颇移和引力的综合作用．本文用光子输运方程方法，针对洛仑兹型发射谱线，求出在Schwarzschild度规下谱线轮廓的精确解，并讨论了Hercules星系团中类星体1604＋179光谱的认证．

The light, originally in Lorentz spectral type, emitted from a luminous Keplerian ring around a black hole should be affected by Doppler shift and gravitational redshift and deflection. A double-peaked line profile should be received by a faraway observer. The precise solution of line profile is obtained in the Schwarzschild case in this paper. The emission spectrum identification of the quasar 1604+179 in the hercules Cluster is also discussed according to the relative intensity of the two peaks in the double-peaked profile.
