Abstract:
We have used 46 high-resolution echelle spectra of the Wolf-Rayet
star HD 192163 taken in 2005-2009 at the Cassegrain focus of the 2-m
Zeiss-2000 telescope of the Shamakha Astrophysical Observatory to
study profiles of the five strongest emission lines (HeII 4859,
HeII 5411, CIV 5808, HeI 5875, (HeII+Halpha) 6560). We also obtained
four echelle spectrograms of the Wolf-Rayet star HD 191765 for a
comparative study of the NaI 5890 (D2) and NaI 5896 (D1) interstellar
absorption lines. The echelle spectrograms were reduced using the
DECH20 code. We determined the equivalent widths, radial velocities,
central intensities, and half-widths of the emission lines. We
We also studied the NaI 5890 (D2) and NaI 5896 (D1) interstellar
absorption lines, which are important for understanding the nature of
the nebula NGC 6888, whose origin is related to HD 192163.
