PSR J1719-1438 b : ウィキペディア英語版
PSR J1719-1438 b


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 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.
==Observational history==

PSR J1719-1438 was first observed in 2009 by a team headed by Matthew Bailes of Swinburne University of Technology in Melbourne, Australia. The orbiting planet was published in the journal ''Science'' on August 25, 2011.〔 The planet was confirmed through pulsar timing, in which small modulations detected in the highly regular pulsar signature are measured and extrapolated.〔 Observatories in Britain, Hawaii, and Australia were used to confirm these observations.〔
