Swift follow-up observations of unclassified ASCA sources
N. Degenaar, R. L. C. Starling, P. A. Evans +11
We present Swift follow-up observations of a sample of 35 unclassified faint X-ray sources drawn from the ASCA Galactic centre and plane surveys. Our short pointed XRT observations…
Evidence for crust cooling in the transiently accreting 11-Hz X-ray pulsar in the globular cluster Terzan 5
N. Degenaar, E. F. Brown, R. Wijnands
The temporal heating and subsequent cooling of the crusts of transiently accreting neutron stars carries unique information about their structure and a variety of nuclear reaction…
The accretion-heated crust of the transiently accreting 11 Hz X-ray pulsar in the globular cluster Terzan 5
N. Degenaar, R. Wijnands
We report on a Chandra Director's Discretionary Time observation of the globular cluster Terzan 5, carried out ~7 weeks after the cessation of the 2010 outburst of the newly discov…
Quiescent X-ray variability from the neutron star transient Aql X-1
E. M. Cackett, J. K. Fridriksson, J. Homan +2
A number of studies have revealed variability from neutron star low-mass X-ray binaries during quiescence. Such variability is not well characterised, or understood, but may be a c…
Implications of burst oscillations from the slowly rotating accreting pulsar IGR 17480-2446 in the globular cluster Terzan 5
Y. Cavecchi, A. Patruno, B. Haskell +6
The recently-discovered accreting X-ray pulsar IGR J17480--2446 spins at a frequency of ~11 Hz. We show that Type I X-ray bursts from this source display oscillations at the same f…
The soft quiescent spectrum of the transiently accreting 11 Hz X-ray pulsar in the globular cluster Terzan 5
N. Degenaar, R. Wijnands
We report on the quiescent X-ray properties of the recently discovered transiently accreting 11 Hz X-ray pulsar in the globular cluster Terzan 5. Using two archival Chandra observa…
