Rxte Observations of the First Transient Z Source Xte J1701–462: Shedding New Light on Mass Accretion in Luminous Neutron Star X-ray Binaries
We report on the first ten weeks of Rossi X-ray Timing Explorer observations of the X-ray transient XTE J1701–462. Large count rate variations were accompanied by changes in the source’s spectral and variability properties. Based on comparisons with other sources we conclude that XTE J1701–462 had all the characteristics of the neutron star Z sources, i.e., the class of the brightest persistent...
متن کاملType I X-ray Bursts from the Neutron-star Transient Xte J1701-462
The neutron-star X-ray transient XTE J1701-462 was observed for ∼3 Ms with RXTE during its 2006-2007 outburst. Here we report on the discovery of three type-I X-ray bursts from XTE J1701462. They occurred as the source was in transition from the typical Z-source behavior to the typical atoll-source behavior, at ∼ 10% of the Eddington luminosity. The first burst was detected in the Z-source flar...
متن کاملSpectral States of Xte J1701 – 462: Link between Z and Atoll Sources
We have analyzed 866 Rossi X-ray Timing Explorer observations of the 2006–2007 outburst of the accreting neutron star XTE J1701−462, during which the source evolves from super-Eddington luminosities to quiescence. The X-ray color evolution first resembles the Cyg X-2 subgroup of Z sources, with frequent excursions on the horizontal and normal branches (HB/NB). The source then decays and evolves...
متن کاملAsca Observations of the Jet Source Xte J 1748 − 288
XTE J1748−288 is a new X-ray transient with a one-sided radio jet. It was observed with ASCA on 1998/09/06 and 1998/09/26, 100 days after the onset of the radio-X-ray outburst. The spectra were fitted with an attenuated power-law model, and the 2–6-keV flux was 4.6

بسیاری از دبیران و دانش آموزان بر این باورند که یادگیری لغات آسان است و شیوه های مختلفی برای یادگیری وجود دارد گرچه یادآوری لغات پس از مدت طولانی بسیار دشوار و پرزحمت است . هدف از این تحقیق آن است که تاثیر استراتژی های حافظه بر روی نگهداری بلند مدت لغات در زبان آموزان خانم سطح متوسط در ایران را بررسی کند. قبل از شروع تدریس، آزمون تعیین سطحی به منظور داشتن زبان آموزان یک سطح برگزار شده و بر اساس...
