A New SU UMa-Type Dwarf Nova, QW Serpentis (= TmzV46)
D. Nogami, M. Uemura, R. Ishioka +11
We report on the results of the QW Ser campaign which has been continued from 2000 to 2003 by the VSNET collaboration team. Four long outbursts and many short ones were caught duri…
Short time-scale X-ray variability of Active Galactic Nuclei
Alexander V. Halevin
In this work we have investigated short time-scale variability of NGC 4051 and NGC 4388. The quasi-steady QPO's time scale of 392017 sec was detected for NGC 4051. For the cas…
High precision effective temperatures for 181 F--K dwarfs from line-depth ratios
V. V. Kovtyukh, C. Soubiran, S. I. Belik +1
Line depth ratios measured on high resolution (R=42000), high S/N echelle spectra are used for the determination of precise effective temperatures of 181 F,G,K Main Sequence stars…
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 spectrum of the roAp star HD 101065(Przybylski's star) in the Li I 6708 A spectral region
A. V. Shavrina, N. S. Polosukhina, Ya. V. Pavlenko +8
We carried out a detailed analysis of spectra of the unique roAp star HD 101065 (Przybylski's star) near the resonance doublet Li I 6708 A, using a most complete line list includin…
Radial Velocity Variations in Pulsating Ap Stars. II. 33 Librae
David E. Mkrtichian, Artie P. Hatzes, Antonio Kanaan
We present precise relative radial velocity (RV) measurements for the rapidly oscillating Ap (roAp) star 33 Librae measured from high resolution data spanning the wavelength interv…
