微透镜搜索有两个同时升起的太阳的行星
Microlensing Search for Planets with Two Simultaneously Rising Suns
摘要：
在迄今发现的200多颗太阳系外行星候选者中，没有已知的行星围绕正常的双星运行。在本文中，我们证明了微透镜是一种可以探测此类行星的技术。这些行星的微透镜发现是可能的，因为行星和宿主双星在双星的质心周围的共同区域产生扰动，因此行星和双星的特征可以在高放大率微透镜事件的光变曲线中检测到。最佳探测系统的行星和双星分离的范围取决于行星质量。对于一颗质量为1000亿的行星，我们发现对于距离双星$\sim$ 0.15 AU - 0.5 AU的双星，位于$\sim$ 1 AU -5 AU范围内的行星具有较高的探测效率
英文摘要：
Among more than 200 extrasolar planet candidates discovered to date, there is no known planet orbiting around normal binary stars. In this paper, we demonstrate that microlensing is a technique that can detect such planets. Microlensing discoveries of these planets are possible because the planet and host binary stars produce perturbations at a common region around center of mass of the binary stars and thus the signatures of both planet and binary can be detected in the light curves of high-magnification microlensing events. The ranges of the planetary and binary separations of systems for optimal detection vary depending on the planet mass. For a Jupiter-mass planet, we find that high detection efficiency is expected for planets located in the range of $\sim$ 1 AU -- 5 AU from the binary stars which are separated by $\sim$ 0.15 AU -- 0.5 AU
