Two X-ray pulsars : 2S 1145-61.9 and 1E 1145.1-6141.
Abstract
Observations from the Einstein Observatory reveal a previously unreported source, 1E 1145.1-6141, within 15 arc min of 2S 1145-619 and of comparable intensity during 1979 July. Periodicity analysis of the data shows a 290 + or - 2 s period for the 2S source and a 298 + or - 4 s period for the 1E source, confirming the previous Ariel 5 report of two periods in this range from this region of the sky.
