Journal ArticleDOI
Relativistic lines and reflection from the inner accretion disks around neutron stars
Edward M. Cackett,Jon M. Miller,David R. Ballantyne,Didier Barret,Sudip Bhattacharyya,Martin Boutelier,M. Coleman Miller,Tod E. Strohmayer,Rudy Wijnands +8 more
TL;DR: In this paper, a comprehensive analysis of the spectra of 10 neutron star low-mass X-ray binaries (LMXBs) is presented, all of which display broad asymmetric Fe K emission lines.

TL;DR: In this paper, the authors present the potential of the Enhanced X-ray Timing and Polarimetry (eXTP) mission for determining the nature of dense matter; neutron star cores host an extreme density regime which cannot be replicated in a terrestrial laboratory.
Journal ArticleDOI
Constraints on Neutron Star Parameters from Burst Oscillation Light Curves of the Accreting Millisecond Pulsar XTE J1814–338
Sudip Bhattacharyya,Tod E. Strohmayer,M. Coleman Miller,Craig B. Markwardt,Craig B. Markwardt +4 more
TL;DR: In this article, a detailed study of the light curves of 22 bursts was performed and the burst oscillation light curves were fit with fully general relativistic models that include light bending and frame dragging for light curve calculation and numerically computed the structure of neutron stars using realistic equations of state.
Journal ArticleDOI
Determining neutron star masses and radii using energy-resolved waveforms of x-ray burst oscillations
TL;DR: In this article, the authors used the energy-dependent waveforms of the X-ray flux oscillations seen during some thermonuclear bursts from some neutron stars to constrain the mass M and radius R of neutron stars.
Journal ArticleDOI
Measurement of neutron star parameters: A review of methods for low-mass X-ray binaries
TL;DR: In this paper, the authors review the methods based on: (1) thermonuclear X-ray bursts, (2) accretion-powered millisecond-period pulsations, (3) kilohertz quasi-periodic oscillations; (4) broad relativistic iron lines; (5) quiescent emissions; and (6) binary orbital motions.
