  • PSR J1719-1438 b is an extrasolar planet that was discovered on August 25, 2011 in orbit around PSR J1719-1438, a millisecond pulsar. The pulsar planet is most likely composed largely of crystalline carbon, but with a density far greater than diamond. PSR J1719-1438 b and PSR J1719-1438 were formerly two stars in a binary star system, but after PSR J1719-1438 went supernova and became a pulsar, PSR J1719-1438 b expanded into its red giant phase and diminished into a white dwarf. The intense conditions of the system converted the white dwarf into a planet composed largely of elements like carbon and oxygen. PSR J1719-1438 b orbits so closely to its host star, the planet's orbit would fit inside the Sun. The existence of such carbon planets had been theoretically postulated.
  • PSR J1719-1438b ist ein extrasolarer Planet, der am 25. August 2011, in einer Umlaufbahn um PSR J1719-1438, einen Millisekunden-Pulsar, entdeckt wurde.
  • PSR J1719-1438 bは、ミリ秒パルサー、PSR J1719-1438の周りを公転する太陽系外惑星である。
