中文拼音 [chāoxīngxì]
超星系
英文
hypergalaxy-
The supernova explosion disrupts the binary.

本文正是在銀河系化學演化的基礎上,利用銀河系的三成分( threezone ) (即暈、厚盤和薄盤)多相( multi - phase ) (氣體,分子云,大、小質量恆星以及剩餘物質)的化學演化的理論模型,通過與觀測約束(質量面密度、場星的年齡-金屬豐度關系、太陽附近g矮星金屬含量分佈函數、三成份的特徵量、元素的星系化學演化、超新星的爆炸率、內落速率等)的比較,來檢驗模型的合理性。In 1987, the brightest supernova in recent history occurred in the large magellanic clouds
1987年,近代歷史上最明亮的超新星出現在大麥哲倫星系。The most recent supernova visible by naked eyes was the sn1987a, which is located in a small nearby galaxy, the large magellanic cloud
近年來可以用肉眼看到的超新星爆發,發生在一個稱為大麥哲倫雲的小星系內的sn1987a 。On february 23, 1987, astronomers got the next best thing : a supernova in one of the milky way ' s satellite galaxies, the large magellanic cloud
在1987年2月23日,天文學家獲得了次佳的機會:銀河系的衛星星系大麥哲倫雲中,發生了一次超新星爆發。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。But almost all spiral galaxies are much older than 2 billion years
但是幾乎所有旋渦星系的年齡都超過了20億年。Shara ' s research interests include stellar collisions, novae and supernovae, and the populations of stars that inhabit star clusters and galaxies
夏拉的研究興趣包括恆星碰撞、新星與超新星,以及星團和星系內恆星的數目分佈。The hot gas will be heated further by any supernova which go off in the galaxy.
熱氣體將被星系中爆發的任何超新星進一步加熱。These supersensitive images have uncovered galaxies that existed when the universe was only a few hundred million years old, about 5 percent of its present age
這些超高解析度影像揭露了在宇宙年齡只有數百萬年,約今日年齡的5 %時就已存在的星系。Topics include : planets, planet formation ; stars, the sun, " normal " stars, star formation ; stellar evolution, supernovae, compact objects ( white dwarfs, neutron stars, and black holes ), plusars, binary x - ray sources ; star clusters, globular and open clusters ; interstellar medium, gas, dust, magnetic fields, cosmic rays ; distance ladder ; galaxies, normal and active galaxies, jets ; gravitational lensing ; large scaling structure ; newtonian cosmology, dynamical expansion and thermal history of the universe ; cosmic microwave background radiation ; big - bang nucleosynthesis

范登柏希特別著迷於盤形星系與星系中心超大質量黑洞的形成過程。This thesis mainly concentrates on the orientations of the spin vectors ( svs ) with different samples of the field galaxies in the local supercluster ( lsc ) and of the galaxies in the virgo cluster, with the context of the origin and formation of galaxies and clusters. we also statistically studied the intrinsic flatness of the disk galaxies
本文主要對本超星系團中的場星系、不同樣本來源的virgo團成員星系的旋轉矢量方向分佈情況進行統計分析,以期尋找星系或星系團等宇宙大尺度結構的形成和起源信息,並給已有的或新的星系或星系團形成和起源理論提供觀測依據和實驗佐證。Clusters of galaxies, in turn, are grouped in larger structures called superclusters
星系群再往上組成更大的結構稱為超星系群。The largest scale on which the mass density has been measured with any precision is that of superclusters
已經用任何精密測量的質量密度的最大值是超星系團的數值。The supercluster - like pipe - type structure is not only the bearing structure for the construction but also determines the space form inside the construction
超星系團般的管狀構築物,既是建築的承重結構,又決定著建築內部的空間形態。This effect is seen as a deviation from the uniform hubble expansion of the galaxies and provides a measure of the mean density within the virgo supercluster
這作用被視為背離銀河哈勃膨脹的統一而提供對室女座超星系團內平均密度的測量。There is reason to believe that our milky way is itself an outlier of the big virgo cluster, responsive to its steady gravitational pull : part of a supercluster
有理由相信我們的銀河系是大室女座星系團的外層星系,響應著一個超星系團的一部分的穩定的引力。分享友人
