Though some ideas of quark stars were proposed as early as in 1969 , no great progress had been made until the 1980s 雖然天文學(xué)家早在1969年便提出奇異星的概念,但直至80年代,這個(gè)理論才有更進(jìn)一步的發(fā)展。
Such sources are believed to be either quark stars or neutron stars , and a subclass of these are already observed by conventional means as pulsars or x - ray emitting celestial objects 一般認(rèn)為這些信號(hào)源就是夸克星或中子星,其中一些已經(jīng)通過傳統(tǒng)的方法觀測(cè)到,稱為脈沖星。
Gravitational waves are ripples in the fabric of space and time produced by events in our galaxy and throughout universe , such as black hole collisions , shockwaves from the cores of exploding supernovas , and rotating pulsars , neutron stars , and quark stars 引力波是時(shí)空結(jié)構(gòu)的波動(dòng),由我們銀河系乃至整個(gè)宇宙中發(fā)生的事件,比如黑洞碰撞、超新星爆發(fā)時(shí)核心產(chǎn)生的激波以及旋轉(zhuǎn)的脈沖星、中子星和夸克星所產(chǎn)生。
A quark star or strange star is a hypothetical type of exotic star composed of quark matter, or strange matter. These are ultra-dense phases of degenerate matter theorized to form inside particularly massive neutron stars.
