  3. 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，當從一個恆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。
  4. 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，不少恆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

  6. Nature of the universe - chapter thirteen our sun is a single star with approximately constant brightness. in fact, in the universe, many stars are not alone, they interact with each other to form binary or multiple star systems

    我們的太陽在太空中孤獨地發放穩定的光芒，但在宇宙中，很多星星並不會單獨地存在，而是和其它恆星組成雙星或甚至多重星系統。
  7. 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。
  8.

    課程的主題包含了：行星、行星形成；恆星、太陽、正常的恆星、恆星形成；恆星演化、超新星、緻密天體（白矮星、中子星及黑洞） 、波霎、雙x -射線源；星團、球狀及疏散星團；星際介質、氣體、塵埃、磁場、宇宙射線；距離階梯；星系、正常及活躍星系、噴流；重力透鏡；大尺度結構；牛頓宇宙學、宇宙的動力膨脹及溫度發展歷史；宇宙背景微波輻射；大霹靂核合成。
  9. 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恆星爆發： （ 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，那是一顆恆星崩潰時幾乎把它所有物質都拋出去了。
  10. 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。
  11. An x - ray binary system has been formed, and the neutron star has made the crucial second step toward becoming a millisecond pulsar

    射線雙星就這樣形成了，於是這顆中子星就向成為毫秒脈沖星邁出了關鍵的第二步。
  12. Such a process can take place in the low mass x - ray binary systems where the mass transfer from the companion to the neutron star can be larger than 0. 5 solar masses. if the neutron star in the low mass x - ray binary accretes the matter, the central densities can reach to a state that strange - matter seeds are formed in the interiors of the star

    在這個系統內，中子星可能會吞噬超過0 . 5個太陽質量的伴星物質，當中子星吸收了這些物質后，中心的密度會增加至足以產生奇異物質種子，這些種子會開始吞噬四周的中子物質，釋放出大量中微子和反中微子，令星體冷卻。
  13. Studies show that, in a binary system, huge energy is released when matter of companion star fall onto the surface of neutron star. on the contrary, when matter falls into black hole, it together with the energy generated will disappear behind the event horizon. for that reason, x rays emitted by neutron star binaries are stronger and their spectra exhibit special characteristics

    研究發現，在雙星系統中，伴星的物質掉落中子星的表面時會釋放巨大能量，而物質掉落黑洞時，則會與它所擁有能量一同消失於視界之中因此含有中子星的雙星系統所發出的x射線強度總是較高，而光譜也有不同的特徵。
  14. The discovery of isolated black holes agrees with the stellar evolution theory that black hole can be formed naturally when a massive star collapses under its own gravitation. binary system is not a necessary for its formation

    黑洞可以孤立地存在，暗示著黑洞並不一定需要存在於雙星系統，而可以透過孤立的大型恆星的重力塌縮而產生，這正是一直以來恆星演化理論所預期的結果。
