Abstract
- We present the results of an analysis of the time variability of the soft X-ray transient GRO J0422+32 (Nova Per 1992) observed with BATSE. Our analysis covers the entire ∼200 day outburst, beginning with the first detection of the source on 1992 August 5. We obtained power density spectra (PDS) in the 20–100 keV energy band covering the frequency interval 0.002–0.488 Hz. The PDSs of GRO J0422+32 show a peak of quasi-periodic oscillations (QPOs) with a centroid frequency of ∼200 mHz, during the first 120 days of the outburst.
