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…
The Pre-He White Dwarfs in Eclipsing Binaries. IV. WASP 1814+48 with Multiperiodic Pulsations
Jae Woo Lee, Kyeongsoo Hong, Hye-Young Kim +1
For the EL CVn candidate 1SWASPJ181417.43+481117.0 (WASP 1814+48), we secured the first spectroscopic observations between 2015 April and 2021 March. Using the echelle spectra, the…
Period Changes of 14,127 Contact Eclipsing Binaries in the Galactic Bulge
Kyeongsoo Hong, Jae Woo Lee, Jang-Ho Park +5
We present the orbital period variations of 14,127 contact eclipsing binaries (CEBs) based on the OGLE-III\&IV observations in the Galactic bulge. New times of minimum lights for t…
V608 Cassiopeiae: A W UMa-type eclipsing binary with two possible circumbinary companions
Jang-Ho Park, Jae Woo Lee
We present the photometric properties of V608 Cas from detailed studies of light curves and eclipse timings. The light curve synthesis indicates that the eclipsing pair is an overc…
The Pre-He White Dwarfs in Eclipsing Binaries. III. WASP 1625-04
Jae Woo Lee, Kyeongsoo Hong, Jang-Ho Park
1SWASP J162545.15-043027.9 (WASP 1625-04) has been announced as one of EL CVn candidates showing total primary eclipses and ellipsoidal variations. This paper presents the absolute…
