PSR J0348+0432 is a pulsar–white dwarf binary system in the constellation Taurus. It was discovered in 2007 with the National Radio Astronomy Observatory's Robert C. Byrd Green Bank Telescope in a drift-scan survey. The notable feature of this binary pulsar is its combination of high neutron-star mass and short orbital period: 2 hours and 27 minutes.This allowed a measurement of the orbital decay due to the emission of gravitational waves, as observed for PSR B1913+16 and PSR J0737−3039.

  • PSR J0348+0432是一個位於金牛座的中子星和白矮星組成的聯星系。該聯星系由綠堤望遠鏡於2007年的飄移掃描巡天中發現。 2011年天文學家宣布該系統中子星的質量是,是發現至今質量最高的中子星。它的質量是結合電波計時和白矮星伴星的光譜精確量測而得知的。這個質量是稍高的值,但和使用引力时间延迟效应得知質量的相比較之下,兩者在統計上並沒有明顯區別。這項量測確認使用不同方式可以確認大質量中子星的存在。 這個脈衝星聯星系統的顯著特徵就是高質量中子星和只有2小時27分的短周期。這允許科學家可以量測因為軌道衰減產生的重力波,類似的狀況還有PSR B1913+16和PSR J0737-3039。 (zh)

  • PSR J0348+0432 è una stella di neutroni facente parte di un sistema binario con una nana bianca. Si trova nella costellazione del Toro, alla distanza di circa 2 100 pc. È stata scoperta nel 2007 dal Radiotelescopio di Green Bank. Nel 2013 è stata annunciata una misurazione accurata della sua massa, che è risultata essere di 2,01 ± 0,04 M☉. È stato possibile ottenenere tale precisione tramite l'analisi dei segnali radio provenienti dalla pulsar e della spettroscopia della nana bianca sua compagna. (it)
