Description We propose a series of 1 ksec Chandra observations of an enigmatic class of
objects: faint to very faint accreting slow pulsators with period greater than
several hundreds of seconds. The nature of these objects is unclear; likely they
are neutron stars accreting from a high-mass companion star, but often an
accreting magnetized white dwarf nature (i.e., an intermediate polar) cannot be
excluded. With our proposed Chandra observations we will obtain a position of
these sources which will be used to identify their optical/IR counterpart,
crucial in determining the exact nature of these systems. In addition, we
request short (5 ksec) XMM-Newton observations of the same targets which will
result in good spectra and allow for searches to be undertaken for any spin-period derivatives.

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.
