Discovery of a kilohertz quasi-periodic oscillation in 2S 0918‒549

We report the discovery of a kilohertz quasi-periodic oscillation (kHz QPO) in the low-mass X-ray binary (LMXB) 2S 0918-549. The kHz QPO has a frequency of 1156 ± 9 Hz, an FWHM of 70 ± 20 Hz, and a fractional rms amplitude of 18% ± 2%. We also detected for the first time a type I X-ray burst in this...
