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…
Thermonuclear (type-I) X-ray bursts observed by the Rossi X-ray Timing Explorer
Duncan K. Galloway, Michael P. Muno, Jacob M. Hartman +2
We have assembled a sample of 1187 thermonuclear (type-I) X-ray bursts from 48 accreting neutron stars by the Rossi X-ray Timing Explorer, spanning more than ten years. The sample…
High-Resolution X-ray Spectroscopy of the Interstellar Medium II: Neon and Iron Absorption Edges
Adrienne M. Juett, Norbert S. Schulz, Deepto Chakrabarty +1
We present high-resolution spectroscopy of the neon K-shell and iron L-shell interstellar absorption edges in nine X-ray binaries using the High Energy Transmission Grating Spectro…
A Debris Disk Around An Isolated Young Neutron Star
Zhongxiang Wang, Deepto Chakrabarty, David L. Kaplan
Pulsars are rotating, magnetized neutron stars that are born in supernova explosions following the collapse of the cores of massive stars. If some of the explosion ejecta fails to…
Detection of Highly Ionized Metal Absorption Lines in the Ultracompact X-ray Dipper 4U 1916-05
Adrienne M. Juett, Deepto Chakrabarty
We present the high-resolution Chandra X-ray Observatory persistent (non-dip) spectrum of 4U 1916-05 which revealed narrow absorption lines from hydrogenic neon, magnesium, silicon…
The neutron star soft X-ray transient 1H1905+000 in quiescence
P. G. Jonker, C. G. Bassa, G. Nelemans +3
In this Paper we report on our analysis of a ~25 ksec. Chandra X-ray observation of the neutron star soft X-ray transient (SXT) 1H1905+000 in quiescence. Furthermore, we discuss ou…
