Renewed activity of the neutron star X-ray transient SAX J1747.0-2853
An X-ray transient was detected in outburst on 18 October 2005 during one of our Chandra/HRC-I observations as part of the XMM-Newton/Chandra monitoring...
Renewed activity of the very faint X-ray transient CXOGC J174535.5-290124 and continued activity of the neutron-star X-ray transient SAX J1747.0-2853
On 8-9 September 2006, a series of 7 XMM-Newton observations were performed as part of our XMM-Newton/Chandra monitoring campaign of the 1.7 square degree...
Renewed optical and X-ray activity in IGR J00291+5934
We report a re-brightening of the millisecond X-ray pulsar IGR J00291+5934. In August the source performed an outburst which was detected in X-ray, UV and...
RXTE Detects 245 Hz X-ray Pulsations from IGR J17511-305
RXTE PCA Bulge scans detected activity of what appeared to be a known source. However, based on the results presented below, and the report of a new INTEGRAL...
After the recent report of X-ray re-brightening (ATel #2608), RXTE has observed the peculiar neutron star X-ray binary Cir X-1 eleven times during the last two...
The neutron star transient SAX J1750.8-2900 has been in outburst since March 15th, 2008 (ATel #1425). The X-ray flux started to decay around mid May and fell...
Self-consistent models for Coulomb heated X-ray pulsar atmospheres
Calculations of accreting magnetized neutron star atmospheres heated by the gradual deceleration of protons via Coulomb collisions are presented. Self...
SN 1988A in M58 - Departure from Co-56 decay 700 days after explosion
Observations of SN 1988A in M58 are presented which show a remarkable departure from Co-56 decay in the optical light curve starting about 700 days since...
