凌日期间引力透镜效应的新观测

New observable for gravitational lensing effects during transits

Shinta Kasuya, Mitsuhiko Honda, Risa Mishima

摘要:

我们研究太阳系外行星凌日时的引力透镜效应。我们重点研究了凌日前后光变曲线的“上升尖峰”现象,这是引力透镜的一个独特特征,并发现它可能是一种新的观测量,可以用来确定物理参数。这种影响的可检测性也进行了讨论。

英文摘要:

We investigate gravitational lensing effects of an extrasolar planet transiting its host star. We focus on the `rising spikes' of the light curve just before and after the transit, which is a peculiar feature of the gravitational lensing, and find that it could be a novel observable for determining physical parameters. Detectability of such an effect is also discussed.
