OJ 287:广义相对论及以后的新试验场

OJ 287: New Testing Ground for General Relativity and Beyond

C. Sivaram

摘要:

本文讨论了超大质量短周期黑洞双星OJ 287作为广义相对论和交变引力理论的一个新的精密试验场。就像双星系统一样,相对论引力效应比太阳系中的大得多。例如,观测到的轨道进动是每周期40度。引力辐射的能量损失与典型的耀变体电磁辐射相当,比双星脉冲星大10个数量级,在光变曲线中已经明显地看到了明显的轨道收缩。这已经在宇宙学距离上的物体上测试了爱因斯坦引力的百分之几。交替重力理论的约束,以及可能的检测长期影响的暗物质和暗能量对这个系统进行了说明。

英文摘要:

The supermassive short period black hole binary OJ287 is discussed as a new precision testing ground for general relativity and alternate gravity theories. Like in the case of binary pulsars, the relativistic gravity effects are considerably larger than in the solar system. For instance the observed orbital precession is forty degrees per period. The gravitational radiation energy losses are comparable to typical blazar electromagnetic radiation emission and it is about ten orders larger than that of the binary pulsar with significant orbit shrinking already apparent in the light curves. This already tests Einstein gravity to a few percent for objects at cosmological distances. Constraints on alternate gravity theories as well as possible detection of long term effects of dark matter and dark energy on this system are described.
