A Photometric and Spectroscopic Study of the Short-Period Algol EW Boötis with a Sct Pulsator
Hye-Young Kim, Kyeongsoo Hong, Chun-Hwey Kim +4
In this paper, we present TESS photometry and high-resolution spectra of the short-period Algol EW Boo. We obtained double-lined radial velocities (RVs) from the time-series spectr…
Photometric study and absolute parameters estimation of six totally eclipsing contact binaries
Kai Li, Qi-Qi Xia, Chun-Hwey Kim +6
High precision CCD observations of six totally eclipsing contact binaries were presented and analyzed. It is found that only one target is an A-type contact binary (V429 Cam), whil…
KMT-2019-BLG-1715: planetary microlensing event with three lens masses and two source stars
Cheongho Han, Andrzej Udalski, Doeone Kim +61
We investigate the gravitational microlensing event KMT-2019-BLG-1715, of which light curve shows two short-term anomalies from a caustic-crossing binary-lensing light curve: one w…
KMT-2018-BLG-1025Lb: microlensing super-Earth planet orbiting a low-mass star
Cheongho Han, Andrzej Udalski, Chung-Uk Lee +32
We aim to find missing microlensing planets hidden in the unanalyzed lensing events of previous survey data. For this purpose, we conduct a systematic inspection of high-magnificat…
Spin Change of Asteroid 2012 TC4 probably by Radiation Torques
Hee-Jae Lee, Josef Ďurech, David Vokrouhlický +9
Asteroid 2012 TC4 is a small (10 m) near-Earth object that was observed during its Earth close approaches in 2012 and 2017. Earlier analyses of light curves revealed its exci…
Physical Nature of the Eclipsing δ Scuti Star AO Serpentis
Jang-Ho Park, Jae Woo Lee, Kyeongsoo Hong +2
We present the absolute properties of the eclipsing binary AO Ser with a pulsating component from our photometric and high-resolution spectroscopic observations, which were pe…
