Description The propeller effect should cut off accretion in fast-spinning neutron star
high-mass X-ray binaries at low mass transfer rates. Accretion seems to be
continuing in some HMXBs observed at Lx < 1e34 ergs/s, as evidenced by
continuing pulsations. However, indications of spectral softening in systems in
the propeller regime suggest that some high-mass X-ray binaries are undergoing
fundamental changes in their accretion regime. We propose to use XMM to measure
the minimum Lx in three quiescent systems known to be in the propeller regime,
look for pulsations in deep quiescence, and study their spectral shape,
particularly looking for blackbody components from the poles or complete neutron
star surface.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
