The ultra-compact Low Mass X-ray Binary (LMXB) X1916-053, composed of a neutron star and a semi-degenerated white dwarf, exhibits periodic X-ray dips with variable width and depth. We have developed new methods to parameterize the dip to systematically study its variations. This helps to further understand binary and accretion disk behaviors. The RXTE 1998 observations clearly show a 4.87d peri...

We report the discovery of a highly coherent oscillation in a type-I X-ray burst observed from 4U 1916−053 by the Rossi X-ray Timing Explorer (RXTE ). The oscillation was most strongly detected ≈ 1 s after the burst onset at a frequency of 269.4 Hz, and it increased in frequency over the following 4 seconds of the burst decay to a maximum of ≃272 Hz. The total drift of 3.5 Hz represents the lar...

The black hole candidate XTE J1817-330 was discovered in outburst on 26 January 2006 with RXTE/ASM. One year later, on 28 February 2007, another X-ray transient discovered in 1996, XTE J1856+053, was detected by RXTE during a new outburst. We report on the spectra obtained by XMM-Newton of these two black hole candidates.
