X-ray Dip Monitoring of Xb 1916-053
We report on the long term monitoring of X-ray dips from the ultracompact low-mass X-ray binary (LMXB) XB 1916-053. Roughly one-month interval observations were carried out with the Rossi X-ray Timing Explorer (RXTE) during 1996, during which the source varied between dim, hard states and more luminous, soft states. The dip spectra and dip lightcurves were compared against both the broadband lu...
متن کاملTiming Analysis of the Light Curve of the Dipping - Bursting X - ray Binary X 1916 - 053
We present the timing analysis results for our observations of the x-ray dip source X1916-053 conducted with RXTE between February and October of 1996. Our goal was to finally measure the binary period-as either the x-ray dip period or ∼1% longer optical modulation period, thereby establishing if the binary has a precessing disk (SU UMa model) or a third star (triple model). Combined with histo...
متن کامل00 2 v 1 1 A ug 1 99 7 Simple Photoelectric Absorption during Dipping in the ASCA Observation of XB 1916 - 053
We report results of analysis of the ASCA observation of the Low Mass X-ray Binary dipping source XB 1916-053 made on 1993, May 2nd, during which dipping was very deep such that in the deepest parts of dips, the X-ray intensity in the band 0.5-12.0 keV fell to zero, demonstrating that all emission components were completely removed. The best-fit orbital period of the binary system determined fr...
متن کاملA study of the spectral evolution during dipping in XB 1323–619 with Rossi-XTE and BeppoSAX
We report results from analysis of the observations of the dipping low mass X-ray binary XB 1323−619 made with BeppoSAX and Rossi-XTE. The dust-scattered halo contributes significantly in this source, and the observation made with BeppoSAX on 1997 August was used to provide MECS radial intensity profiles at several energies. From these, the halo fractions were obtained and thus an optical depth...
متن کاملNeutral absorber dips in the periodic burster LMXB XB 1323 - 619 from Suzaku
We present results of an observation with Suzaku of the dipping, periodic bursting low mass X-ray binary XB 1323-619. Using the energy band 0.8-70 keV, we show that the source spectrum is well-described as the emission of an extended accretion disk corona, plus a small contribution of blackbody emission from the neutron star. The dip spectrum is well-fitted by the progressive covering model in ...
