Title Investigating the properties of a new ms. pulsar with a Jovian mass companion

Author Dr Andrea Possenti
Description A binary msp with a planetary mass companion has been recently discovered. For a psr mass of 1.4Msun, we infer a companion mass of 1.3 Jovian masses, which is ten times smaller than that of any other known stellar companion to a msp. This psr is likely the first long-sought example of a msp which descended from an Ultra Compact Accreting X-ray MSP. In the context of a multi-wavelength campaign, we request a 25 ks exposure (sampling 3 orbits of the system) with the aims of:i) identifying the X-ray counterpart;ii) comparing X-ray fluxes and spectra with those of other binaries with other kinds of companions and-or have undergone other evolutionary paths;iii) searching for orbital variations in the X-ray flux, in order to investigate if the new binary can be the progenitor of an isolated msp.

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.
