| Description | This report covers the period January 15, 1993 through ROSAT Guest Investigator Program, for the August 1, 1993 for NASA grant NAG5-1684 project 'ROSAT Observations of the Binary received the standard output for both the initial Be-star/Radio Pulsar PSR1259-63'. We have now 10,713 second observation of PSR1259-63 (which occurred during 8/30/92 - 9/4/92) and the subsequent 36,108 second observation (during 2/7 - 16/93). The source was detected at the rate of 0.02 counts per second, or about 200 total photons in the first observation, and at about 0.03 counts per second for a total of 1200 additional photons during the second observation. In addition, significant variability, both temporal and spectral has occurred during the second data set. No pulsations at the radio period were found, with upper limits of 5-10 percent. This is in marked contrast to the lack of detection in observations made by Bailes et al., during AO2 on 2/28/92. |
