Electron density and carriers of the diffuse interstellar bands
P. Gnacinski, J. K. Sikorski, G. A. Galazutdinov
We have used the ionisation equilibrium equation to derive the electron density in interstellar clouds in the direction to 13 stars. A linear relation was found, that allows the de…
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…
The Rotational Excitation Temperature of the 6614 Diffuse Interstellar Band Carrier
J. Cami, F. Salama, J. Jiménez-Vicente +2
Analysis of high spectral resolution observations of the 6614 diffuse interstellar band (DIB) line profile show systematic variations in the positions of the peaks in the substr…
Stellar abundance patterns. What is the possible level of completeness today ?
V. Gopka, A. Yushchenko, F. Musaev +6
We discuss the way of increasing of the number of chemical elements, investigated in stellar spectra. We can reach it by using spectrum synthesis method, new atomic data and observ…
The chemical composition of a mild barium star HD202109
A. V. Yushchenko, V. F. Gopka, Chulhee Kim +3
We present the result of chemical abundances of a mild barium star HD202109 (zeta Cyg) determined from the analysis of spectrum obtained by using a 2-m telescope at the Peak Tersko…
The spectral variations of the O-type runaway supergiant HD 188209
G. Israelian, A. Herrero, F. Musaev +4
We report spectral time series of the late O-type runaway supergiant HD 188209. Radial velocity variations of photospheric absorption lines with a possible quasi-period ~ 6.4 days…
Discovery of the secondary star of the HgMn binary kappa Cancri
T. Ryabchikova, O. Kotchoukhov, G. Galazutdinov +2
A careful investigation of a CCD spectrum of the SB1 system kappa Cnc in the spectral region 3800 A - 8000 A resulted in the discovery of the lines of the secondary star. We then a…
