astro-ph.EP2025★ 38 cited

Microlensing events indicate that super-Earth exoplanets are common in Jupiter-like orbits

Weicheng Zang, Youn Kil Jung, Jennifer C. Yee +65

Exoplanets classified as super-Earths are commonly observed on short period orbits, close to their host stars, but their abundance on wider orbits is poorly constrained. Gravitatio…

MOA-2022-BLG-033Lb, KMT-2023-BLG-0119Lb, and KMT-2023-BLG-1896Lb: Three low mass-ratio microlensing planets detected through dip signals

Cheongho Han, Ian A. Bond, Youn Kil Jung +45

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. We conducted detailed modeling of the light curves t…
