PSR J1719-1438b

PSR J1719 - 1438b is an extrasolar planet that was discovered on August 25, 2011, in orbit around PSR J1719 -1438, a millisecond pulsar.

Character

PSR J1719 - 1438b has a diameter of 60,000 kilometers ( about half as large as that of Jupiter ) with a minimum density of 23 grams per cubic centimeter. The Planet of the central pulsar is quite possibly the most part of crystalline carbon or diamond. PSR J1719 -1438 b and PSR J1719 -1438 were probably used to be two stars in an ultra-compact low-mass X -ray binary ( LMXB UC ) binary star system. After PSR J1719 -1438 exploded as a supernova and became a slowly rotating pulsar, PSR J1719 -1438 b went into a red giant phase and by continuing matter transfer to the pulsar beyond the stage of the white dwarf in the "naked" core of the tool on while the pulsar by the constant matter incidence angular momentum resumed and accelerated to millisecond pulsar. Due to the intense conditions of the system of the white dwarf that is converted into a planet, which is composed mainly of heavy elements such as carbon and oxygen. PSR J1719 -1438 b orbits its star at a distance of 600,000 km, which is so narrow that the orbit of the planet would fit in the sun. Furthermore, the planet just 2 hours, 10 minutes and 37.0237 seconds (average error: 20 microseconds) needs to circle around PSR J1719 -1438. The existence of such diamond planet was postulated theoretically.
