HEAO-1 and Infrared Observations of the X-Ray Pulsar 1E:2259+586
Abstract
The analysis of HEAO-1 scanning observations of the X-ray pulsar 1E2259+586 from 1978 is reported. The period at this epoch was 6.978586 more or less 0.000006s, consistent with an extrapolation of the spindown trend. The luminosity and pulse profile are similar to those of subsequent observations. Deep IR images of the region of 1E2259+586 are presented. No new counterparts are discovered. The possibility that 1E2259+586 is a massive, heavily reddened system can be discounted. The implications of these results are discussed in terms of evolutionary models and an explanation for the observed spindown is proposed.
