X-ray Timing of Neutron Stars, Astrophysical Probes of Extreme Physics
Z. Arzoumanian, S. Bogdanov, J. Cordes +11
The characteristic physical timescales near stellar-mass compact objects are measured in milliseconds. These timescales -- the free-fall time, the fastest stable orbital period, an…
Chandra X-Ray Observatory Observations of the Globular Cluster M71
R. F. Elsner, C. O. Heinke, H. N. Cohn +12
We observed the nearby, low-density globular cluster M71 (NGC 6838) with the Chandra X-ray Observatory to study its faint X-ray populations. Five X-ray sources were found inside th…
Thermal X-rays from Millisecond Pulsars: Constraining the Fundamental Properties of Neutron Stars
Slavko Bogdanov, Jonathan E. Grindlay, George B. Rybicki
Abridged) We model the X-ray properties of millisecond pulsars (MSPs) by considering hot spot emission from a weakly magnetized rotating neutron star (NS) covered by an optically-t…
An X-ray View of Radio Millisecond Pulsars
Slavko Bogdanov, Jonathan E. Grindlay
In recent years, X-ray observations with Chandra and XMM-Newton have significantly increased our understanding of rotation-powered (radio) millisecond pulsars (MSPs). Deep Chandra…
Comptonization in the X-ray Spectra of Radio Millisecond Pulsars
Slavko Bogdanov, Jonathan E. Grindlay, George B. Rybicki
The majority of X-ray-detected rotation-powered millisecond pulsars (MSPs) appear to exhibit predominantly thermal emission, believed to originate from the heated magnetic polar ca…
Constraints on Neutron Star Properties from X-ray Observations of Millisecond Pulsars
Slavko Bogdanov, George B. Rybicki, Jonathan E. Grindlay
We present a model of thermal X-ray emission from hot spots on the surface of a rotating compact star with an unmagnetized light-element atmosphere. An application to ROSAT, Chandr…
