Microlensing path parametrization for Earth-like Exoplanet detection around solar mass stars

arXiv:1809.10230 · doi:10.3847/1538-3881/aadc68

Abstract

We propose a new parametrization of the impact parameter u0 and impact angle α for microlensing systems composed by an Earth-like Exoplanet around a Solar mass Star at 1 AU. We present the caustic topology of such system, as well as the related light curves generated by using such a new parametrization. Based on the same density of points and accuracy of regular methods, we obtain results 5 times faster for discovering Earth-like exoplanet. In this big data revolution of photometric astronomy, our method will impact future missions like WFIRST (NASA) and Euclid (ESA) and they data pipelines, providing a rapid and deep detection of exoplanets for this specific class of microlensing event that might otherwise be lost.
