    一個由拉斐特的路易斯安娜大學物理學教授約翰?馬泰塞領導的小組證實了一個想法,那就是它最有可能是一顆褐矮星,這是一種永遠也不能積聚足夠的質量著火燃燒的星,它只是在太空中數十億年地無焰悶燒。
  9. Based on the viewpoint of interaction between waves in plasmas, the partial differential equation that causes the spectral lines broadening has been deduced from radiation transfer equation of high - frequency electromagnetic waves in plasmas. the numerical solution has been obtained by using the fortran program we compiled. we concretely calculated the spectral lines widths of and fraunhoferx 3704 in corona, fj / a4923. 9 in dwarf nova oy car and f. / a4934 in the variable star rr lyrae

  10. That is the following in essence. a sufficient mass of cold matter will necessarily collapse to a black hole, and stars with different mass will evolve into the white - dwarf - star, the neutron - star or the black - hole eventually because of the radiation of the burning core. the collapse of stars with sufficient mass leads to a black hole endowed with mass and charge and angular momentum, no other adjustable parameters : " a black hole has no hair.

    第二章簡單介紹一下「黑洞無毛」理論形成,即足夠質量的冷物質能夠塌縮成黑洞,不同質量的恆星由於核燃燒輻射最終會演化成為白矮星、中子星或黑洞,以及黑洞的終態系統唯一地由質量、電荷和角動量確定,而無其它物理參數,此即為「黑洞無毛」理論。
  11. The dark star ? ? named nemesis by astronomers ? ? is thought to be a brown dwarf " that i round the sun in an orbit so large it is measured in light years, the distance light travels in a year, equivalent to about 6, 000 billion miles

    這顆被天文學家叫做復仇女神星的暗星被認為是一顆"褐矮星" ,它圍繞太陽旋轉的軌道大得要用光年計量,光年是光在一年中走過的距離,大約等於6萬億英里。
  12. The dark star ? ? named nemesis by astronomers ? ? is thought to be a brown dwarf " that spins round the sun in an orbit so large it is measured in light years, the distance light travels in a year, equivalent to about 6, 000 billion miles

    這顆被天文學家叫做復仇女神星的暗星被認為是一顆"褐矮星" ,它圍繞太陽旋轉的軌道大得要用光年計量,光年是光在一年中走過的距離,大約等於6萬億英里。
  13. The evolution of fixed star having something to do with nuclear reaction, the star generally loses partial mass in its final period and finally collapses into compact star ( white dwarf, neutron star or black hole )

    恆星的演化與核反應有關,演化到晚期的恆星一般要損失一部分質量,然後坍縮成緻密星(白矮星、中子星或黑洞) 。
  14. The disrupted sunlike star could form a massive disk in orbit around the dwarf

    瓦解的類太陽恆星可能在環繞白矮星的軌道上形成一個質量巨大的盤狀物。
  15. If the mass of the core after a supernova explosion is more than 1. 4 but less than about 3 solar masses, then electron degenerate pressure is not strong enough to support the star. the star will contract to a size even smaller than the white dwarf. the electrons are squeezed into the nuclei and are combined with the protons to form neutrons

    假若在超新星爆發后,剩餘核心質量介乎太陽質量的1 . 4至3倍,那麼核心中的電子簡並壓力便再不足以抵抗強大的引力,恆星會進一步收縮,直至電子亦被擠壓至原子核內,和質子結合成為中子。
  16. After 100, 000 to one million years, depending on the original mass of the star, it ceases altogether, and the remnant star settles down as an extremely dense and hot white dwarf ? a stellar ember crushed by gravity into a nearly crystalline orb about the size of earth

    經過10 ~ 100萬年(取決于恆星的原始質量) ,恆星風將驟然終止,而恆星的殘留物會演變成極緻密高熱的白矮星:一種被重力擠壓成地球般大小,近乎晶質球體的恆星遺骸。
