planetary microlensing event Archives

Light curve the lensing event MOA-2022-BLG-033 and the model curve. The lower panel offers a comprehensive view of the event, while the upper panel provides a close-up view of the anomaly (the region enclosed by a box in the lower panels). The colors of the data points correspond to the telescopes listed in the legend. The bottom two panels show the residuals from the models with and without considering microlens-parallax effects. -- astro-ph.EP

Three Low Mass-ratio Microlensing Planets Detected Through Dip Signals

by Keith CowingJanuary 18, 2025

We examined the anomalies in the light curves of the lensing events MOA-2022-BLG-033, KMT-2023-BLG-0119, and KMT-2023-BLG-1896.

Light curves of the microlensing event OGLE-2015-BLG-1609 with three microlensing model topologies for positive values of the impact parameter u0. The difference between the topologies is visible only during the planetary anomaly (HJD ∼ 2457270; see Fig. 2). The photometry comes from the OGLE, MOA, RoboNet, and MiNDSTEp projects. -- astro-ph.EP

OGLE-2015-BLG-1609Lb: Sub-jovian Planet Orbiting A Low-mass Stellar Or Brown Dwarf Host

by Keith CowingDecember 18, 2024December 18, 2024

We present a comprehensive analysis of a planetary microlensing event OGLE-2015-BLG-1609. The planetary anomaly was detected by two survey telescopes, OGLE and MOA.
