KIC 11401845: An Eclipsing Binary with Multiperiodic Pulsations and Light Travel Time
Jae Woo Lee, Kyeongsoo Hong, Seung-Lee Kim +1
We report the photometry of KIC 11401845 displaying multiperiodic pulsations, superimposed on binary effects. Light-curve synthesis represents that the binary star i…
KIC 6220497: A New Algol-type Eclipsing Binary with Multiperiodic Pulsations
Jae Woo Lee, Kyeongsoo Hong, Seung-Lee Kim +1
We present both binarity and pulsation of KIC 6220497 from the {\it Kepler} observations. The light curve synthesis shows that the eclipsing system is a semi-detached Algol with pa…
Apsidal motions of 90 eccentric binary systems in the Small Magellanic Cloud
K. Hong, J. W. Lee, S. -L. Kim +2
We examined light curves of 1138 stars brighter than 18.0 mag in the band and less than a mean magnitude error of 0.1 mag in the band from the OGLE-III eclipsing binary cat…
A Super-Jupiter Microlens Planet Characterized by High-Cadence KMTNet Microlensing Survey Observations of OGLE-2015-BLG-0954
I. -G. Shin, Y. -H. Ryu, A. Udalski +26
We report the characterization of a massive (m_p=3.9 +- 1.4 M_jup) microlensing planet (OGLE-2015-BLG-0954Lb) orbiting an M dwarf host (M=0.33 +- 0.12 M_sun) at a distance toward t…
Time-series spectroscopy of the pulsating eclipsing binary XX Cephei
Jae-Rim Koo, Jae Woo Lee, Kyeongsoo Hong +2
Oscillating Algol-type eclipsing binaries (oEA) are very interesting objects that have three observational features of eclipse, pulsation, and mass transfer. Direct measurement of…
