Precise Radial Velocities of Polaris: Detection of Amplitude Growth
Byeong-Cheol Lee, David. E. Mkrtichian, Inwoo Han +2
We present a first results from a long-term program of a radial velocity study of Cepheid Polaris (F7 Ib) aimed to find amplitude and period of pulsations and nature of secondary p…
The BOES spectropolarimeter for Zeeman measurements of stellar magnetic fields
Kang-Min Kim, Inwoo Han, Gennady G. Valyavin +9
We introduce a new polarimeter installed on the high-resolution fiber-fed echelle spectrograph (called BOES) of the 1.8-m telescope at the Bohyunsan Optical Astronomy Observatory,…
The Lorentz force in atmospheres of CP stars: Aurigae
D. Shulyak, G. Valyavin, O. Kochukhov +7
Several dynamical processes may induce considerable electric currents in the atmospheres of magnetic chemically peculiar (CP) stars. The Lorentz force, which results from the inter…
Interplay between diffusion, accretion and nuclear reactions in the atmospheres of Sirius and Przybylski's star
Alexander Yushchenko, Vera Gopka, Stephane Goriely +8
The abundance anomalies in chemically peculiar B-F stars are usually explained by diffusion of chemical elements in the stable atmospheres of these stars. But it is well known that…
