tification is very important, albeit complex because of the d ifficulty in measuring orbital periods in low mass X-ray binaries. The ultracompact low-mass X-ray binary 4U 0513-40 in the globular cluster NGC1851 reveals a clear sinusoidal periodic signal with a period of∼17 minutes when the source is in a typical high /soft state with a dominant soft thermal component (using Bep poSAX and Chandra data). The periodicity disappears when the sour ce is in a low/hard state and the
