چکیده

We present low and intermediate resolution spectroscopy of the optical counterpart to the recently discovered pulsating X-ray source 1WGA J1958.2+3232. The presence of strong H i, He i and He ii emission lines together with the absence of absorption features rules out the possibility that the object is a massive star, as had recently been suggested. The observed X-ray and optical characteristics are consistent with the object being an intermediate polar. The double-peaked structure of the emission lines indicates that an accretion disc is present.

The discovery of 12 min X – ray pulsations from 1 WGA J 1958 . 2 + 3232

During a systematic search for periodic signals in a sample of ROSAT PSPC (0.1– 2.4 keV) light curves, we discovered ∼ 12 min large amplitude X–ray pulsations in 1WGA J1958.2+3232, an X–ray source which lies close to the galactic plane. The energy spectrum is well fit by a power law with a photon index of 0.8, corresponding to an X–ray flux level of ∼ 10−12 erg cm−2 s−1. The source is probably ...
