Planeta Pulsaris: Corpora astronomica
Planeta pulsaris est planeta qui circum pulsar (i.e.
Primi inventi planetae extrasolares fuerunt planetae pulsarium.
Hi per mensuras periodi pulsationum, enormitates quaerendo, deteguntur. Quaelibet enim corpora caelestia quae circum pulsar moveantur sunt causa mutationum eius ordinariae periodi, et cum pulsaria constante frequentia pulsare soleant, quaelibet mutatio, auxilio accuratarum mensurarum periodi pulsationis, facilie revelatur.
Historia
Inventio planetarum pulsarium fuit insperata: stellae neutronicae in principio supernovis creatae sunt, et quilibet planeta tales stellas prius orbitans in explosione destruendus putabar. Anno 1991, Andreas G. Lyne primum planetam pulsaris inventum nuntiavit circa PSR B1829–10, sed hoc nuntium postea retractavit, parum ante quam reales primi planetae pulsarium nuntiarentur. Nam anno 1992, Alexander Wolszczan et Dale Frail inventionem systematis pluribus planetis circa pulsar PSR B1257+12 nuntiaverunt. Hi (planetae c et d) fuerunt primi duo certi planetae extrasolares, eorum fuit primum systema planetarium extrasolare pluribus planetis notum, et ei primi planetae pulsarium detecti. In principio inventio fuit incerta propter priorem retractationem alterīus pulsaris planetae, et multi astronomi inquirebant quomodo pulsaria habere possent planetas. Demum tamen planetae probati sunt esse reales, et postea, eadem arte, duo alii planetae minoribus massis in eadem systemate inventi sunt, licet retractatus sit unus (planeta b servatur).
