Sun-Ju Chung,Cheongho Han,Byeong-Gon Park,Doeon Kim,Sangjun Kang,Yoon-Hyun Ryu,Kang-Min Kim,Y.-B. Jeon,Dong-Wook Lee,Kyongae Chang,Woo-Baik Lee,Yong Hee Kang +11 more
TL;DR: In this paper, the authors derived analytic expressions for the location, size, and shape of the central caustic as a function of the star-planet separation, s, and the planet/star mass ratio, q, under the planetary perturbative approximation and compared the results with those based on numerical computations.

TL;DR: In this paper, the authors studied a sample of 93 asteroid pairs, i.e., pairs of genetically related asteroids that are on highly similar heliocentric orbits, and derived the absolute magnitude differences of the studied asteroid pairs that provided their mass ratios q.
Journal ArticleDOI
Gravitational Microlensing: A Tool for Detecting and Characterizing Free-Floating Planets
Cheongho Han,Sun-Ju Chung,Doeon Kim,Byeong-Gon Park,Yoon-Hyun Ryu,Sangjun Kang,Dong Wook Lee +6 more
TL;DR: In this paper, a similar observational setup was used for the mass determinations of free-floating planets with masses ranging from several Earth masses to several Jupiter masses, which are the populations of planets that have not been previously probed.
Journal ArticleDOI

TL;DR: In this article, a high-angular-resolution imaging survey of 42 large main-belt asteroids with VLT/SPHERE/ZIMPOL was conducted to constrain the formation and evolution of a representative sample of large asteroids.
Journal ArticleDOI
The Possibility of Detecting Planets in the Andromeda Galaxy
Sun-Ju Chung,Doeon Kim,M. J. Darnley,J. P. Duke,Andrew Gould,C. Han,Y.-B. Jeon,E. Kerins,A. M. Newsam,Byeong-Gon Park +9 more
TL;DR: In this article, the authors investigate the feasibility of using a survey to detect planets in M31, and estimate the efficiency of detecting signals produced by planets with various masses and separations from the host star.
