Spectroscopic characteristics of 1H2214+589/3G71: 3G71 may be a Herbig Ae/Be star.
Abstract
The authors present evidences showing that the Be star 3G71, proposed as the optical counterpart of the Be/X-ray binary source 1H2214+589, may be a Herbig Ae/Be star. These evidences can be summarized as follows. The authors made spectroscopic observations by using a CCD spectrograph with dispersions 50 Å/mm and 195 Å/mm at the BAO 2.16 m telescope. Analysis of the optical spectra of 3G71 is given. The authors have performed cross-identification between the HST GSC catalogue and the IRAS Point Source Catalogue and found the IRAS point source counterpart of 3G71 to be 2248+6058. Using Palomar sky survey map, they have made a search for a nebulosity in the immediate vicinity of 3G71 and actually discovered a bright nebula, at whose center 3G71 is just located. It is concluded from the characteristics of 3G71 mentioned above that 3G71 may be a Herbig Ae/Be star.
