Microlensing Detections of Moons of Exoplanets
Cheongho Han
We investigate the characteristic of microlensing signals of Earth-like moons orbiting ice-giant planets. From this, we find that non-negligible satellite signals occur when the pl…
A Characteristic Planetary Feature in Double-Peaked, High-Magnification Microlensing Events
Cheongho Han, B. Scott Gaudi
A significant fraction of microlensing planets have been discovered in high-magnification events, and a significant fraction of these events exhibit a double-peak structure at thei…
Discovery of a Jupiter/Saturn Analog with Gravitational Microlensing
B. S. Gaudi, D. P. Bennett, A. Udalski +66
Searches for extrasolar planets have uncovered an astonishing diversity of planetary systems, yet the frequency of solar system analogs remains unknown. The gravitational microlens…
Microlensing Search for Planets with Two Simultaneously Rising Suns
Cheongho Han
Among more than 200 extrasolar planet candidates discovered to date, there is no known planet orbiting around normal binary stars. In this paper, we demonstrate that microlensing i…
Color-Shift Measurement in Microlensing-Induced Stellar Variation from Future Space-Based Surveys
Byeong-Gon Park, Cheongho Han
If a microlensing event is caused by a star, the event can exhibit change in color due to the light from the lens. In the previous and current lensing surveys, the color shift coul…
