PSR J1719-1438

PSR J1719 -1438 is a millisecond pulsar with a spin period of 5.7 ms and is located about 4000 light years from Earth in the direction of the snake. Millisekundenpulsare are at the beginning of normal pulsars, which from a companion star evolve through uptake of matter into a millisecond pulsar. The planet was discovered with the 64 -meter Parkes radio telescope in Australia.

To PSR J1719 -1438 circles of so-called diamonds Planet. The researchers noted in the signal from PSR J1719 -1438 small disturbances, caused by the gravity of a low-mass companion. This pet has a diameter of 60,000 miles and orbits PSR J1719 -1438 in just 2 hours and 10 minutes at a distance of 600,000 kilometers. This proximity to the pulsar 's companion should really be torn, but its density is so high that it is still intact.

" The density of the planet is at least as high as that of platinum and tells us much about its origin ," says the leader of the team, Matthew Bailes of Swinburne University of Technology in Australia.

It is assumed that the companion of the core of a " white dwarf " is who has made 99.9 % of its mass to the pulsar ( neutron star ). The leftover remnant of the companion consists mainly of carbon and oxygen in crystalline form.
