binary stars are the strongest and most predictable sources of gravitational waves 雙星是最強(qiáng)最可預(yù)測的引力波源。
A binary star is a double star, consisting of two stars turning round each other 雙星是兩顆星,是由相互圍繞旋轉(zhuǎn)的兩顆星組成。
The most convincing evidence of black holes comes from research into binary star systems 黑洞最強(qiáng)有力的證據(jù)來自對雙星系的研究。
Binary systems in which both components can be seen are called visual binary stars :若雙星中所有成員皆可以看得到,我們便稱之為目視雙星。
His earliest interest came from observing binary stars with surplus world war ii binoculars 他對天文的最早興趣,始自于用第二次世界大戰(zhàn)剩馀物資中的雙筒望遠(yuǎn)鏡觀測雙星。
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(gè)恒星逃出的氣體被另一個(gè)星體的重力捕獲時(shí),也會(huì)形成盤狀結(jié)構(gòu)。
This requires even more detectors because these waves are even weaker than the waves from binary stars and neutron stars 這將需要更多的探測器,因?yàn)榕c雙星和中子星產(chǎn)生的引力波相比,這些引力波還要更弱。
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(huì)在相互的引力下互相繞著對方運(yùn)行,假若系統(tǒng)只有兩顆星,我們會(huì)稱之為
There are basically five types of binary stars, according to how the binary systems are discovered . thus, some systems could belong to more than one type 根據(jù)雙星發(fā)現(xiàn)的經(jīng)過,我們可以把雙星分為五類,有些雙星系統(tǒng)可同時(shí)屬于超過一種類型。
Waves from binary stars are mostly low frequency waves; this makes their signals hard to separate from the earth's gravitational field and vibrations in the earth 它們發(fā)出的引力波大多數(shù)是低頻率的,這就使這些引力波難以和地球引力場的震蕩區(qū)分。
