Hakucho observation of the pulse period of GX 301-2 and confirmation of the orbital parameters.
Abstract
We present the results of a timing analysis of the X-ray pulsar GX 301-2 observed by the Hakucho satellite. The outbursts from GX 301-2 were observed on two occasions during April and May of 1982 in agreement with the predicted ephemeris of flare recurrence based on the period of 41.5 d. Our timing analysis as well as these recurrences confirm an orbital period of 41.5 d. A large value of intrinsic spin-down is implied.
