      This is the first such measurement of an interacting binary system through the gamma-ray emission of a millisecond pulsar. The scientists make full use of the Fermi-LAT time resolution, which is a. The authors report the discovery of kHz fluctuations, including quasi-periodic oscillations (QPO) at {approximately} Hz and {approximately} Hz and a broadband kHz continuum in the power density spectrum of the high mass X-ray binary pulsar Centaurus X-3 (Jernigan, Klein and Arons ).

      Discovered on Octo as part of the Monitor of All-sky X-ray Image (MAXI) experiment, MAXI J is a transient pulsar in a high-mass X-ray binary (HMXB) system. On Novem The gamma-ray binary system PSR B/LS , originally discovered in a high-frequency radio survey devoted to the detection of young and short-period pulsars [19], consists of a rapidly rotating neutron star with a spin period of about 48 ms and a spin-down luminosity ∼ 10 35 erg s − 1.

Yeah, so OK. That's a lot of jargon. Tell you what: Let's tackle it right to left. First, what's a pulsar? A pulsar is special kind of neutron star. OK, what's a neutron star? It's the über-dense.

There were 6 sources originally proposed for analysis: SMC X-1, A, LMC X-1, LMC X-3, (these 3 sources are all located in the Large Magellanic Cloud region), 4UO+63 and 4U Results on these sources are summarized.

This report covers the period September 1, through August 1, for NASA grant NAG through the Astrophysics Data Program (ADP), for the project 'High Time Resolution Studies of Binary X-ray Pulsars'.

Accreting X-ray pulsars are among the most luminous objects in the X-ray sky. In highly magnetized neutron stars (B~10^12 G), the flow of matter is dominated by the strong magnetic field.

The general properties of accreting X-ray binaries are presented, focusing on the spectral characteristics of the systems. The use of cyclotron lines as a tool to directly measure a neutron star's magnetic Cited by: 3.

Watts, David John'X-ray and optical studies of binary x-ray pulsars', PhD thesis, University of : David John Watts. Abstract. As X-ray astronomy enters the Einstein era when faint, distant, and exotic X-ray sources are being investigated, we thought it might be useful to review some of the progress made over the past decade on a class of relatively nearby objects that have contributed richly to our understanding of astrophysics — the binary X-ray pulsars.

Several new features of X-ray binary pulsars are revealed from recent observations with ASCA, RXTE, BeppoSAX and other X-ray observatories. Among these, I will review in this paper some recent progress in spectroscopic studies of accreting X-ray pulsars in binary systems (XBPs).

First, I will discuss soft excess features observed in the energy spectra of XBPs and propose that it is a common. We report on a 39 ks observation of the s low-mass X-ray binary pulsar 4U with the High Energy Transmission Grating Spectrometer (HETGS) on the Chandra X-Ray Observatory.

These include the pulsar with the fastest rotation period (in the globular cluster Terzan 5; Hessels et al. ), the double pulsar system (Burgay et al. ; Lyne et al. ) and its impressive tests of general relativity (Kramer et al. ), the ‘missing link’ between the low-mass X-ray binaries and the MSPs (Archibald et al.

X-ray binaries are a class of binary stars that are luminous in X-rays are produced by matter falling from one component, called the donor (usually a relatively normal star), to the other component, called the accretor, which is very compact: a neutron star or black infalling matter releases gravitational potential energy, up to several tenths of its rest mass, as X-rays.

Evolutionary scenarios for Her X-1, MXB4UGX 1 + 4, 1E +   Radio pulsars with millisecond spin periods are thought to have been spun up by the transfer of matter and angular momentum from a low-mass companion star during an x-ray–emitting phase.

The spin periods of the neutron stars in several such low-mass x-ray binary (LMXB) systems have been shown to be in the millisecond regime, but no radio pulsations have been detected.

The idea for organizing an Advanced Study Institute devoted largely to neutron star timing arose independently in three places, at Istanbul, Garching and Amster­ dam; when we became aware of each other's ideas we decided to join forces.

The choice of a place for the Institute, in Turkey, appealed. Harvard-Smithsonian Center for Astrophysics 60 Garden Street, Cambridge, MA USA Phone: Fax: The present state of X–ray astronomy which has already produced brilliant successes (the observation of powerful X–ray sources – ‘X–ray stars’, including pulsars, and so on) is on the whole in a stage of being established and of fast development and it seems particularly inappropriate to discuss here the available observational data.Indeed, inthe High Time Resolution Universe survey discovered a radio pulsar whose rotational and X-ray properties identified it as a magnetar (Levin et al.

). Here, we present X-ray observations of three high-B radio pulsars: PSRs J−, B−19, and J− These as a group are key sources for X-ray study, as they.
