J/AZh/71/588   Study of Two HgMn Stars             (Zakharova, 1994)

Study of Two HgMn Stars with Suspected Anomalies of Noble Gas Abundances. Zakharova L.A. <Astron. Zh. 71, 588 (1994)> =1994AZh....71..588Z
ADC_Keywords: Stars, peculiar ; Spectroscopy Description: Three spectra of HD182308 (HR 7361) and four spectra of HD178065 (HR 7245) were obtained from 1989 to 1990 with the Main Stellar Spectrograph of the 6-m telescope at the Special Astrophysical Observatory and with the Coude spectrograph of the 2-m telescope of the Rozhen Observatory of the Bulgarian Academy of Sciences. Spectra were obtained in the range of 3700-4900A with inverse dispersion of 9 A/mm. Spectral resolution was close to 0.25A. Elemental abundances of two HgMn stars, HD 178065 and HD 182308, were found.
