  2. On the bases of the galaxy evolution theory, we use the therotical chemical evolution model of three zone ( such as halo, thick disk and thin isk ) and multi - phase ( diffuse gas, molecular clouds, stars of both low and high mass, the remnants ). by comparing with the observational constraints, such assurface densities, age - metallicity relation, g - dwarf metallicity distribution in the solar neighbourhood and the correlation between [ a / fe ] and [ fe / h ], supernovae rates, infall rates. the rationality of the model is verified. based on the theory model, we calculate the abundance of neutron capture element

  4. Nucleated dwarf galaxy

    有核矮星系
  5. In general, ba stars belong to binary system, and their heavy - element overabundances are due to the accreting material from the companions ( the former tp - agb stars and the present white dwarfs ). carrying out a series of monte - carlo simulations, the changes of orbital elements of binaries are recalculated for wind accretion scenario of the total angular momentum conservation

    研究表明，鋇星應該屬于雙星系統，其重元素超豐來自雙星吸積，它的伴星已經經歷了s -過程核合成，而且由在以前發生的同其伴星（以前是agb星，現已演化為白矮星）的質量傳輸過程中，從伴星那裡獲得了富含重元素的物質，這樣造成了鋇星的重元素超豐。
  6. Dwarf spiral galaxy

    矮旋渦星系

    矮星系問題
  15. Nonnucleated dwarf elliptical

    無核矮橢圓星系
  16. 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。
  17. Allowing for selection effect, about 1 per cent of all f and g dwarfs are w uma systems, and so understanding the origin and evolution of w uma stars are of importance for investigations in the evolution of the star clusters and galaxies

    如果考慮了觀測選擇效應的影響，約1左右的f和g型矮星都是wuma型相接雙星。因此，了解wuma型相接雙星的起源和演化對研究星系和星團的演化有十分重要的意義。
  18. They usually consist of old stars. some dwarf ellipticals have as few as 10 million stars, and make them not much different from a large globular cluster

    它們通常包含較年老的恆星，有些矮橢圓星系只有約一千萬顆星，和大球狀星團相差不遠。
  19. More recently, dr. rosanne di stefano also from the harvard - smithsonian centre for astrophysics and i used the chandra x - ray observatory to detect objects dubbed " quasisoft " x - ray sources in nearby galaxies because of their low temperatures, which are at most four million degrees celsius. that is well below the temperatures expected for " hard " x - ray sources such as neutron stars or stellar mass black holes - which run between 10 million and 100 million degrees celsius - and still hotter than " soft " x - ray sources like white dwarfs

    最近羅珊迪史提芬路博士她亦來自哈佛大學史密森天體物理中心和筆者利用錢德拉射線天文臺在鄰近星系偵測到一種奇怪的-射線源，我們稱之為類軟射線源，因為它們的溫度最高只有攝氏400萬度，遠低於一般硬射線源，例如中子星和恆星型黑洞溫度介乎攝氏1千萬至1億度，卻又比軟射線源例如白矮星為高。
  20. Astronomers have identified hundreds of these peculiar beasts, both young ones in star - forming regions and older ones in the neighborhood of our solar system

    天文學家已經觀測到數百顆這樣奇特的怪物，有處在恆星形成區域里的年輕棕矮星，也有位於我們太陽系附近較年老的棕矮星。
