These planets were discovered by the Polish astronomer Aleksander Wolszczan on February 9, 1990, using the Arecibo radio telescope. Other articles where PSR B1257+12 is discussed: planet: Planets of other stars: …rapidly spinning neutron star) called PSR B1257+12. In 1992 Wolszczan and Dale Frailpublished a famous paper on the first confirmed discovery of planets outside our solar system. PSR B1257+12 c, also named Poltergeist, is an extrasolar planet approximately 2,300 light-years away in the constellation of Virgo. [10] In December 2015, the IAU announced the winning names, submitted by the Planetarium Südtirol Alto Adige in Karneid, Italy, were Lich for the pulsar and Draugr, Poltergeist and Phobetor for planets A, B and C, respectively:[6][11], In 2016, the IAU organized a Working Group on Star Names (WGSN)[13] to catalog and standardize proper names for stars (including stellar remnants). PSR B1257+12 b, alternatively designated PSR B1257+12 A, also named Draugr, is an extrasolar planet approximately 2,300 light-years away in the constellation of Virgo.

Template:Planetbox begin Template:Planetbox image Template:Planetbox star Template:Planetbox orbit Template:Planetbox character Template:Planetbox discovery Template:Planetbox reference Template:Planetbox end PSR B1257+12 b (ex PSR B1257+12 A) is an exoplanet (or extrasolar planet) approximately 980 light-years away in the constellation of Virgo. [1], The convention that arose for designating pulsars was that of using the letters PSR (Pulsating Source of Radio) followed by the pulsar's right ascension and degrees of declination. PSR B1257+12, previous designation PSR 1257+12, is a pulsar located 2,300 light years away from the Sun.It is located in the constellation Virgo.. La nomo PSR B1257+12 rilatas al ĝiaj koordinatoj en la epoko B1950.0. [15], The discovery stimulated a search for planets orbiting other pulsars, but it turned out such planets are rare; only four other pulsar planets, orbiting PSR B1620−26, PSR B0943+10, and PSR B0329+54, have been confirmed. 10-5 edit: Age [Gyr] 3.00 edit: Metallicity [Fe/H] N/A: Temperature [K] N/A: Spectral type: Pulsar: Visual magnitude: N/A: Planet sizes. The planet is the innermost object … Wolszczan PSR 1257 + 12 B 的 平 均 日 距 為0 . Masses and orbital inclinations of planets in the PSR B1257+12 system. It is a millisecond pulsar, a kind of neutron star, with a rotation period of 6.22 milliseconds (9,650 rpm), and was found to have anomalies in the pulsation period, which led to investigations as to the cause of the irregular pulses. The modern convention prefixes the older numbers with a B meaning the coordinates are for the 1950.0 epoch. Penamaan PSR B1257+12 merujuk pada koordinatnya dalam epoch B1950.0..

ApJ., 619, 1084 paper. In the first 15 years after these initial discoveries, about 200… The pulsar contains a planetary system which contains three known planets. The entire system is a graveyard, remnants of what used to be a normal, functional solar system before the star blew apart in a giant explosion known as a supernova. This project consists of nine epochs of phase-referenced observations spanning about two years. Media in category "PSR B1257+12 B" The following 3 files are in this category, out of 3 total. It is about twice as massive as the Moon, and is listed as the least massive planet (with the mass accurately determined) known, including among the planets in the Solar System. Ĝi estas la plej proksima planedo ĉirkaŭ la pulsaro PSR B1257+12, do ĝi estas pulsara planedo. PSR B1257+12 (kadang-kadang disingkat PSR 1257+12) adalah sebuah pulsar di rasi Virgo, berlokasi 980 tahun cahaya dari Bumi. Wolszczan used the Arecibo radio telescope in Puerto Rico to find three planets - the first of any kind ever found outside our solar system - circling a pulsar named PSR B1257+12. [20][21][22][23] The dwarf planet hypothesis was also retracted because further observations showed that the pulsation anomalies previously thought to reveal a fourth orbital body are "not periodic and can be fully explained in terms of slow changes in the pulsar's dispersion measure".[22]. 2. In 1996, a possible Saturn-like (100 Earth mass) gas giant was announced orbiting the pulsar at a distance of about 40 AU. All new pulsars have a J indicating 2000.0 coordinates and also have declination including minutes. The planet is the innermost object orbiting the pulsar PSR B1257+12, making it a pulsar planet in the dead stellar system. The pulsar has a planetary system with three known planets, named "Draugr" (PSR B1257+12 b or PSR B1257+12 A), "Poltergeist" (PSR B1257+12 c, or PSR B1257+12 B) and "Phobetor" (PSR B1257+12 d, or PSR B1257+12 C), respectively. [8] In December 2015, the IAU announced the winning name was Draugr for this planet. [7] The process involved public nomination and voting for the new names. PSR B1257+12 estis malkovrita de la pola astronomo Aleksander Wolszczan dum 1990 per la Arecibo radioteleskopo.
