binary system

In addition to the basic concepts of newtonian mechanics , fluid mechanics , and kinetic gas theory , a variety of interesting topics are covered in this course : binary stars , neutron stars , black holes , resonance phenomena , musical instruments , stellar collapse , supernovae , astronomical observations from very high flying balloons ( lecture # 35 ) , and you will be allowed a peek into the intriguing quantum world 除了牛頓力學、流體力學和氣體動力論的一些基本概念外,本課程還包括一些有趣的主題:雙子星、中子星、黑洞、共振、樂器、恒星坍塌、超新星、從飛得很高的氣球上進行天文觀測(第35講) ,并且你能感受到量子世界的迷人魅力。

Using the expression of the quadrupole and octapole radiation power , the multipole radiation power of a special binary star , psr1913 + 16 , are estimated . the results show that its whole power of quadrupole radiation is , which is coincident with the observed results , and that the expected whole power of octapole radiation is 本文用所得到的引力的四極和八極輻射的功率表達式計算了psr1913 + 16脈沖雙星的多極引力輻射,其四極輻射的總功率數量級為,與已經觀測到的間接結果是一致的。

These events include two kinds of stellar explosions : ( 1 ) nova explosions , in which one of the two members of a binary star system hurls dust and gas into space ; ( 2 ) much more violent supernova explosions , in which a star collapses , then throws off most of its matter 這些事件包括兩種類型的恒星爆發: ( 1 )新星爆發,雙星系統中的一員將氣體和塵埃猛烈拋入太空; ( 2 )更為猛烈的超新星爆發,那是一顆恒星崩潰時幾乎把它所有物質都拋出去了。

Sometimes , in a binary star system , one star will pass in front of the other producing what we call eclipsing binary . it can be treated as a special kind of visual binary . eclipsing binary systems are variable stars see below :有些雙星系統,其中一顆星會在另一顆星前經過,產生周期性的光度變化,我們稱這種雙星為食雙星,基本上我們可以把食雙星看成為目視雙星的一種。

Novae are usually binary stars . materials are transferred from one component to another . explosions on or closed to the surface of the recipient star will happen after sufficient material is accumulated 新星通常是雙星,物質會由一顆子星轉移至另一顆子星,當目的地恒星表面上或附近積聚了足夠的物質時,便會發生爆炸。

Contact binary : in these binary stars , components are too close together that they have material exchange . the mutual gravity may also deform the stars and glue them together :這種雙星系統,子星間的距離十分接近,強大的引力不單只把恒星拉扯至變形,更造成子星間出現物質交換,把兩星連接起來。

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射線數據的分析表明,點源與包含有中子星或黑洞(它們正從正常恒星吸走物質)的雙星系統成協。

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的圖像,和被認為包含有黑洞的星系中心區域的圖像。

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 它們發出的引力波大多數是低頻率的,這就使這些引力波難以和地球引力場的震蕩區分。

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 根據雙星發現的經過,我們可以把雙星分為五類,有些雙星系統可同時屬于超過一種類型。

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,假若系統只有兩顆星,我們會稱之為

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,因為與雙星和中子星產生的引力波相比,這些引力波還要更弱。

In some binary star systems , gas escapes from one star and is captured by the gravity of the other to form a disk 某些雙星系統中,當從一個恒星逃出的氣體被另一個星體的重力捕獲時,也會形成盤狀結構。

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剩馀物資中的雙筒望遠鏡觀測雙星。

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。

The most convincing evidence of black holes comes from research into binary star systems 黑洞最強有力的證據來自對雙星系的研究。

A binary star is a double star , consisting of two stars turning round each other 雙星是兩顆星,是由相互圍繞旋轉的兩顆星組成。

Binary stars are the strongest and most predictable sources of gravitational waves 雙星是最強最可預測的引力波源。
