黑矮星 的英文怎麼說
中文拼音 [hēiǎixīng]
黑矮星
英文
[天文學] black dwarf-
Since a 7 - solar - mass is too large to be a white dwarf or neutron star, it must be a black hole
因為有著7個太陽質量的星體不可能是白矮星或中於星，所以它一定是黑洞。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

新出版商矮腳雞書業和黑馬漫畫公司期望能激發星戰迷的想象，他們精雕細刻地運用術語「曼達洛」來吸引廣大讀者的興趣。However, the time taken is much larger than the age of the universe. so, we believe there is no black dwarf yet
但這個過程所需時間比宇宙現在的年更長，所以我們相信宇宙中仍沒有黑矮星的存在。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。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） 。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。The temperature range of quasisoft x - ray sources falls just right for an accreting black hole that is more massive than a stellar - mass black hole. however, we should be cautioned that in principle, the low temperatures of many quasisoft x - ray sources can be explained by stellar - mass black holes, neutron stars, and even white dwarfs under very specific physical conditions
就以類軟射線源的溫度范圍來說，雖然它完全符合那些比恆星型黑洞更大的吸積黑洞，但有一點不能忽略，就是這個溫度在理論上也可以是由恆星型黑洞中子星甚至白矮星在一些特殊物理情況下產生。Venus - who is signified by venus, whether man or woman, hath a goodly and fair round visage, a full eye, usually we say goggle - eyed, red ruddy lips, the neither more thick or bigger then the upper, the eye ? lids black, however lovely and gracefull, the hair of lovely colour ( but most part according to the sign as before repeated ) in some its cole - black, in others a light brown, a soft smooth hair, and the body extream well shaped, ever rather inclining to shortnesse than talnesse
金星-無論是男人還是女人，金星指示他們有漂亮的相貌和臉蛋，圓圓的大眼睛，紅潤的舌頭，兩者比上段的描述的要更厚更大些，眼皮有些發黑，盡管如此也是很優雅可愛的，頭發的顏色動人（但是更多的像前面重復過的星座說明的一樣） ，有些是黑褐色，有些是淺棕色，頭發軟而滑，體形及佳，身高中等不會太高或太矮。分享友人
