EXO 1745-248 is an 11 Hz Eclipsing Pulsar
Abstract
RXTE pointed observations of the ongoing outburst of EXO 1745-284 (ATEL #2919, #2920, #2922, #2924) began at approximately 2010-10-13 at 00:13 UTC, for an exposure of 3.2 ksec. The flux of the source is approximately 95 mCrab (2-10 keV). The observation reveals strong pulsations at a barycentric frequency of 11.0452(2) Hz.
In addition, we observe an eclipse ingress/egress during the observation, beginning at 00:50:24.5 UTC and ending at 00:58:56.2 UTC, implying an eclipse duration of 511.7 ± 1 sec.- Publication:
