Origin of the Long-Period Radial Velocity Variation in the Red Supergiant HD 216946 (V424 Lac)
Byeong-Cheol Lee, Myeong-Gu Park
We present precise radial-velocity (RV) observations of the K-type red supergiant HD~216946 (V424 Lac) obtained over approximately 22 years with the Bohyunsan Optical Astronomy Obs…
A Search for Exoplanets around Northern Circumpolar Stars X. The origin of radial velocity variations in the evolved star HD 216595
Sang-Hee Kim, Byeong-Cheol Lee, Shenghong Gu +9
Detecting planetary companions around evolved stars, particularly asymptotic giant branch (AGB) stars, is challenging due to intrinsic stellar variability such as surface convectio…
Planetary companions in K giants beta Cancri, mu Leonis, and beta Ursae Minoris
B. -C. Lee, I. Han, M. -G. Park +3
Auns. The aim of our paper is to investigate the low-amplitude and long-period variations in evolved stars with a precise radial velocity (RV) survey. Methods. The high-resolution,…
Detection of an exoplanet around the evolved K giant HD 66141
B. -C. Lee, D. E. Mkrtichian, I. Han +2
Aims. We have been carrying out a precise radial velocity (RV) survey for K giants to search for and study the origin of the lowamplitude and long-periodic RV variations. Methods.…
Planetary companions orbiting M giants HD 208527 and HD 220074
B. -C. Lee, I. Han, M. -G. Park
Aims. The purpose of the present study is to research the origin of planetary companions by using a precise radial velocity (RV) survey. Methods. The high-resolution spectroscopy o…
Multisite spectroscopic seismic study of the beta Cep star V2052 Oph: inhibition of mixing by its magnetic field
M. Briquet, C. Neiner, C. Aerts +29
We used extensive ground-based multisite and archival spectroscopy to derive observational constraints for a seismic modelling of the magnetic beta Cep star V2052 Ophiuchi. The lin…
