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

A binary msp with a planetary mass companion has been recently discovered. For apsr mass of 1.4Msun, we infer a companion mass of 1.3 Jovian masses, which isten times smaller than that of any other known stellar companion to a msp. Thispsr is likely the first longsought example of a msp which descended from anUltra Compact Accreting Xray MSP. In the context of a multiwavelengthcampaign, we request a 25 ks exposure (sampling 3 orbits of the system) with theaims of:i) identifying the Xray counterpart;ii) comparing Xray fluxes andspectra with those of other binaries with other kinds of companions and/or haveundergone other evolutionary paths;iii) searching for orbital variations in theXray flux, in order to investigate if the new binary can be the progenitor of an isolated msp. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
