Does the accreting millisecond pulsar XTE J1814-338 precess?
C. T. Y. Chung, D. K. Galloway, A. Melatos
Precession in an accretion-powered pulsar is expected to produce characteristic variations in the pulse properties. Assuming surface intensity maps with one and two hotspots, we co…
Compton Scattering of Fe K alpha Lines in Magnetic Cataclysmic Variables
A. L. McNamara, Z. Kuncic, K. Wu +2
Compton scattering of X-rays in the bulk flow of the accretion column in magnetic cataclysmic variables (mCVs) can significantly shift photon energies. We present Monte Carlo simul…
Intermittent pulsations in an accretion-powered millisecond pulsar
Duncan K. Galloway, Edward H. Morgan, Miriam I. Krauss +2
We describe observations of the seventh accretion-powered millisecond pulsar, HETE J1900.1-2455 made with the Rossi X-ray Timing Explorer during the year of activity that followed…
Discovery of pulsations in the X-ray transient 4U 1901+03
Duncan K. Galloway, Zhongxiang Wang, Edward H. Morgan
We describe observations of the 2003 outburst of the hard-spectrum X-ray transient 4U 1901+03 with the Rossi X-ray Timing Explorer. The outburst was first detected in 2003 February…
A Frequency Glitch in an Accreting Pulsar
D. K. Galloway, E. H. Morgan, A. M. Levine
Frequency glitches have been observed so far only in radio pulsars and anomalous X-ray pulsars. Here we present evidence of a glitch in a neutron star accreting from a Be companion…
Accretion column eclipses in the X-ray pulsars GX 1+4 and RX J0812.4-3114
D. K. Galloway, A. B. Giles, K. Wu +1
Sharp dips observed in the pulse profiles of three X-ray pulsars (GX 1+4, RX J0812.4-3114 and A 0535+26) have previously been suggested to arise from partial eclipses of the emissi…
