摘要: We take advantage of more than 10 years monitoring the eclipsing HMXB systems LMC X-4, Cen X-3, 4U 1700-377, 1538-522, SMC X-1, IGR J18027-2016, Vela J17252-3616, XTE J1855-026, and OAO 1657-415 with ASM on-board RXTE ISGRI INTEGRAL to update their ephemeris. These results are used refine previous measurements orbital period decay all sources (where available) provide first accurate values apsidal advance in X-1 1538-522. Updated for masses neutron stars hosted ten HMXBs also provided, as well long-term lightcurves folded on best determined parameters. reveal complex eclipse ingresses egresses, that understood mostly being due presence accretion wakes. The reported this paper constitute a database be population evolutionary studies HMXBs, theoretical modelling wind-fed X-ray binaries.
