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…
C, N, O, and Na Abundances of Cepheid Variables: Implications on the Mixing Process in the Envelope
Y. Takeda, D. -I. Kang, I. Han +2
With an aim of investigating the nature of evolution-induced mixing in the envelope of evolved intermediate-mass stars, we carried out an extensive spectroscopic study for 12 Cephe…
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.…
Chemical composition of giants from two moving groups
F. Liu, Y. Q. Chen, G. Zhao +4
We present stellar parameters of 19 K-type giants and their abundances of 13 chemical elements (Al, Ba, Ca, Fe, K, Mg, Mn, Na, Ni, Sc, Si, Ti and V), selected from two moving group…
The Lorentz force in atmospheres of CP stars: 56 Arietis
D. Shulyak, O. Kochukhov, G. Valyavin +5
The presence of electric currents in the atmospheres of magnetic chemically peculiar (mCP) stars could bring important theoretical constrains about the nature and evolution of magn…
