Low-amplitude and long-period radial velocity variations in giants HD 3574, 63 Cygni, and HD 216946 (Research Note)
B. -C. Lee, I. Han, M. -G. Park +2
Aims. We study the low-amplitude and long-period variations in evolved stars using precise radial velocity measurements. Methods. The high-resolution, fiber-fed Bohyunsan Observato…
Raman Scattered Ne VII973 at 4881 Å in the Symbiotic Star V1016 Cygni
Hee-Won Lee, Jeong-Eun Heo, Byeong-Cheol Lee
We present the high resolution spectra of the symbiotic star V1016 Cygni obtained with the Bohyunsan Optical Echelle Spectrograph in 2003 and 2005, from which we find a broad emiss…
Planetary companion in K giant Sigma Persei
Byeong-Cheol Lee, Inwoo Han, Myeong-Gu Park +4
We report the detection of an exoplanet candidate in orbit around sigma Persei from a radial velocity (RV) survey. The system exhibits periodic RV variations of 579.8 +/- 2.4 days.…
1SWASP J093010.78+533859.5: A Possible Hierarchical Quintuple System
Jae-Rim Koo, Jae Woo Lee, Byeong-Cheol Lee +5
We present the observational results of this kind of rare object 1SWASP J093010.78+533859.5, for which the doubly eclips- ing feature had been detected previously from the SuperWAS…
