MOA-2020-BLG-135Lb: A New Neptune-class Planet for the Extended MOA-II Exoplanet Microlens Statistical Analysis

We report the light-curve analysis for the event MOA-2020-BLG-135, which leads to the discovery of a new Neptune-class planet, MOA-2020-BLG-135Lb. With a derived mass ratio of q=1.52_{-0.31}^{+0.39} \times 10^{-4} and separation s\approx1, the planet lies exactly at the break and likely peak of the exoplanet mass-ratio function derived by the...
