the most convincing evidence of black holes comes from research into binary star systems 黑洞最強有力的證據(jù)來自對雙星系的研究。
in some binary star systems, gas escapes from one star and is captured by the gravity of the other to form a disk 某些雙星系統(tǒng)中,當(dāng)從一個恒星逃出的氣體被另一個星體的重力捕獲時,也會形成盤狀結(jié)構(gòu)。
many stars orbit around other stars under the mutual gravitational attractions . if two stars orbit around one another, they form a binary star system 在天空中,不少恒星會在相互的引力下互相繞著對方運行,假若系統(tǒng)只有兩顆星,我們會稱之為
but there are images of binary star systems consisting of one normal star and one black hole, and of the central regions of galaxies that are believed to contain black holes 但是有由一個黑洞和一個正常恒星組成的雙子星系統(tǒng)的圖像,和被認(rèn)為包含有黑洞的星系中心區(qū)域的圖像。
analysis of the x-ray data shows that the point sources are associated with binary star systems that contain a neutron star or black hole that is pulling matter away from a normal star 對x射線數(shù)據(jù)的分析表明,點源與包含有中子星或黑洞(它們正從正常恒星吸走物質(zhì))的雙星系統(tǒng)成協(xié)。
