The 1 - 50 keV spectral and timing analysis of IGR J18027-2016: an eclipsing, high mass X-ray binary
A. B. Hill, R. Walter, C. Knigge +9
We report the association of the INTEGRAL source IGR J18027-2016 with the BeppoSAX source SAX J1802.7-2017. IGR J18027-2016 is seen to be a weak, persistent source by the IBIS/ISGR…
Far-Ultraviolet Surveys of Globular Clusters: Hunting for the Products of Stellar Collisions and Near Misses
Christian Knigge
Globular clusters are gravitationally bound stellar systems containing on the order of 100,000 stars. Due to the high stellar densities in the cores of these clusters, close encoun…
First results from multi-wavelength observations during the 2001 outburst of WZ Sge
Erik Kuulkers, Christian Knigge, Danny Steeghs +2
WZ Sge has shown superoutbursts in 1913, 1946 and 1978. On 2001 July 23 a new outburst was announced, about 10 years `too early'. Target of opportunity satellite observations with…
Emission from the secondary star in the old CV WZ Sge
D. Steeghs, T. Marsh, C. Knigge +3
We present the first detection of the mass donor star in the cataclysmic variable WZ Sge. Phase resolved spectroscopy reveals narrow Balmer emission components from the irradiated…
Assisted stellar suicide: the wind-driven evolution of the recurrent nova T Pyxidis
C. Knigge, A. R. King, J. Patterson
We show that the extremely high luminosity of the short-period recurrent nova T Pyx in quiescence can be understood if this system is a wind-driven supersoft x-ray source (SSS). In…
