英文摘要 | Our spectroscopic observation of the Be/X-ray binary LSI+65 degrees 010 showed a dramatic variation in November 1992 with an increase by a factor of more than 3 in the equivalent width of the Her emission line. This supports the view that the primary is a Be star father than a supergiant. A well-defined double-peaked profile in seen in the spectrum of September 1994: while the red peak remained at 6563 Angstrom, the blue one was -7.2 Angstrom to the blue. We suggest that such a profile is caused by the superposition of two emission lines, one from the shell of the Be star, one from an HII region around the neutron star. This provides, for the first time, direct observational evidence for the existence of a HII region around compact object and caused by X-ray emission. On 1992-11-04, the red side of the H-alpha line did not change while the blue side was greatly enhanced. We suggest that this may be caused by the HII region around the neutron star. |
