引力微透镜引起的天体测量位移的相对论修正

Relativistic corrections to astrometric shifts due to gravitational microlensing

Geraint F. Lewis, X. Rosalind Wang

摘要:

引力微透镜已被证明是一种多用途的天体物理学工具。最近,高阶相对论修正是否会影响微透镜的可观测性质的问题已经得到解决。这封信扩展了早期的研究,研究了微透镜事件期间天体测量位移中的高阶相对论项,揭示了它们不会产生任何影响。相对论修正的幅度在天体物理学的背景下进行检查,发现是可以忽略不计的。

英文摘要:

Gravitational microlensing has proved to be a versatile astrophysical tool. Recently, the question of whether higher order relativistic corrections can influence the observable properties of microlensing has been addressed. This letter extends earlier studies, investigating higher order relativistic terms in astrometric shifts during microlensing events, revealing that they produce no effects. The magnitude of the relativistic corrections is examined in an astrophysical context and is found to be negligible.
