TL;DR
This paper discusses the analysis of a microlensing event OGLE-2008-BLG-513, presenting a static binary star model as a simpler explanation, challenging the planetary interpretation and leading to the paper's withdrawal.
Contribution
The paper introduces a static binary star model for OGLE-2008-BLG-513 that competes with the planetary model, highlighting the importance of model simplicity in microlensing analysis.
Findings
The static binary star model has a chi^2 comparable to the planetary model.
The static binary model is simpler according to Occam's Razor.
The paper was withdrawn due to the preference for the simpler model.
Abstract
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 Consequently, this paper has been withdrawn from ApJ.
