Description PSR J2032+4127 is a Fermi and radio pulsar in the Cygnus OB2 association, powering a TeV pulsar wind nebula. It is in a highly eccentric 48 year orbit around a Be star. We propose for time-critical spectroscopic monitoring at periastron to look for the expected interaction of the pulsar with the wind and-or disk of the Be star. XMM-Newton is also able to test for pulsations at the 143 ms spin period that would be the signature of accretion onto the neutron star. These observations are important for comparison with PSR B1259-63, the prototype and only other Be-gamma-ray binary with a known pulsar, as well as to help understand gamma-ray binaries that have compact objects of uncertain type that may be neutron stars even though their pulsations have not been detected.

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.
