摘要:

发现了OGLE-2008-BLG-513的一个静态双星解,其质量比q~0.28,分离度s~0.86。这个模型的chi ^2与本文提出的具有行星质量比和轨道运动的模型的chi ^2相当。由于静态双星透镜模型比本文最初提出的模型更简单,奥卡姆剃刀说这可能是正确的解决方案。因此,本文已从ApJ中撤回。

英文摘要:

A static binary star solution for OGLE-2008-BLG-513 has been found. The mass ratio and separation for this solution are q~0.28, s~0.86. This model has a chi^2 comparable to the chi^2 of the model with a planetary mass ratio and orbital motion that was presented in this paper. Because the model with a static, binary star lens is simpler than the model originally presented in this paper, Occam's Razor says it is likely to be the correct solution. Consequently, this paper has been withdrawn from ApJ.
