    Alternative planet names PSR J1719-14 b
    Description The 5.7ms pulsar PSR J1719-14 shows timing variations on a 2.17 hour timescale. These can be explained with a Jovian planet. However, because of the planet's short distance to the star, its density has to be more then 20 times that of Jupiter. The planet is most likely a remnant of a binary star which avoided complete destruction. The chemical composition, pressure and dimensions of the planet indicate that it is crystallized, or in other words, a very big diamond (Bailes et al 2011).edit
