Title Sleuthing A New Eclipsing Accreting Millisecond Pulsar

Description We have recently discovered a new gamma-ray loud low-mass X-ray binary, 3FGL J0427.9-6704. The X-ray and radio properties of this source suggest it is a transitional millisecond pulsar in the accreting state. Uniquely among members of this class, this source shows optical, X-ray, and gamma-ray eclipses, allowing precise constraints not available for non-eclipsing systems, such as measurements of the binary component masses. Here we propose XMM X-ray and optical observations to better understand the variability in the system and determine how similar its properties are to the other transitional millisecond pulsars.

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.
