A 552Hz X-ray burst oscillation in the accreting neutron star EXO 0748-676
Abstract
We report the detection of millisecond oscillations in the rising phase of two thermonuclear (type-I) X-ray bursts from the low-mass X-ray binary EXO 0748-676, using data taken with the Proportional Counter Array (PCA) on the Rossi X-ray Timing Explorer (RXTE). In a burst on 2007 January 14 14:08:44 UT we detected oscillations at a frequency of 552.02 Hz in a 1-s segment of data, with a Leahy power of 59.7.
