标题： Model dependence of the multi-transonic behavior, stability properties and corresponding acoustic geometry for accretion onto a spinning black hole

摘要： 在后牛顿伪势框架内，已经比较了不同盘几何结构围绕旋转黑洞的多跨音吸积。 详细研究了所有盘模型中静止冲击特性随黑洞自旋的变化，并且在绝热和等温情况下进行了比较。 还研究了这些情况下表面引力随自旋的变化。 显示英文摘要

摘要： Multi-transonic accretion for a spinning black hole has been compared among different disc geometries within post Newtonian pseudo potential framework. The variation of stationary shock characteristics with black hole spin has been studied in details for all the disc models and compared for adiabatic as well as for isothermal scenario. The variations of surface gravity with spin for all these cases have also been investigated.
