Pulsar planets are planets that are orbiting pulsars. The first such planets to be discovered were around a millisecond pulsar in 1992 and were the first extrasolar planets to be confirmed as discovered. Pulsars are extremely precise clocks and even small planets can create detectable variations in pulsar traits; the smallest known exoplanet is ...
X-ray pulsar-based navigation and timing (XNAV) or simply pulsar navigation is a navigation technique whereby the periodic X-ray signals emitted from pulsars are used to determine the location of a vehicle, such as a spacecraft in deep space. A vehicle using XNAV would compare received X-ray signals with a database of known pulsar frequencies ...
These were the first discovery of extrasolar planets to be confirmed; [17] [18] as pulsar planets, they surprised many astronomers who expected to find planets only around main-sequence stars. Additional uncertainty surrounded the system, because of a claim of an earlier pulsar planet around PSR 1829-10 that had to be retracted due to errors in ...
PSR B0943+10 is a pulsar 2,000 light years from Earth [2] in the direction of the constellation of Leo. [4] It was discovered at Pushchino in December 1968, becoming the first pulsar discovered by Soviet astronomers. [5] [6] The original designation of this pulsar was PP 0943. [1]
This is the list of 20 extrasolar planets that were detected by timing –– 8 by pulsar timing and 12 by variable star timing, sorted by orbital periods. It works by detecting the changes in radio emissions from pulsars caused by the gravity of orbiting planets. Same thing works for variable stars, not by radio but light.
PSR B1257+12 b, alternatively designated PSR B1257+12 A, also named Draugr, is an extrasolar planet approximately 2,300 light-years (710 pc) away [4] in the constellation of Virgo. The planet is the innermost object orbiting the pulsar Lich , making it a pulsar planet in the dead stellar system.
PSR B1257+12 c, alternatively designated PSR B1257+12 B, also named Poltergeist, is an extrasolar planet approximately 2,300 light-years away [3] in the constellation of Virgo. It was one of the first planets ever discovered outside the Solar System , [ 4 ] [ 5 ] and is one of three pulsar planets known to be orbiting the pulsar Lich .
PSR B1620-26 b orbits a pair of stars.The primary star, PSR B1620-26, is a pulsar, a neutron star spinning at 100 revolutions per second, with a mass of 1.34 M ☉, a likely radius of around 20 kilometers (0.00003 R ☉) and a likely temperature less than or equal to 300,000 K.
