    恆星風所運載出的質量愈來愈少，使其速度愈來愈快。
  3. We have collected a mass of stellar activity and rotation data of late - type stars. combining with the results of hipparcos satellite, we reserch the relation between stellar activity and rotation ( include rotation period and rossby number ), and discuss the distribution of stellar rotation period and the evolution of angle momentum of late - type stars

    因此，我們收集了晚型恆星的色球和冕球活動的指數以及恆星自轉方面研究發表的大量的觀測資料並結合hipparcos衛星的觀測結果，對晚型恆星的磁活動與恆星自轉間的相關性進行細致的研究。
  4. Nevertheless, there is no direct evidence for intermediate - mass black holes and it will be very difficult to establish them in the same way that we have for supermassive black holes, at the centre of galaxies, or stellar black holes

    畫家筆下的xmm -牛頓衛星鳴謝： esa可惜的是，一些用來印證星系中心超重黑洞或恆星型黑洞存在的方法，很難套用於中型黑洞上。
  5. Most astronomers are convinced of the existence of the so - called stellar black holes, which collapse out of single star and have masses up to 10 times that of the sun. a famous example of this kind of black holes is cygnus x - 1. likewise, supermassive black holes, which can have the mass of billions of stars and sit in the centre of galaxies, are also believed to exist

    一向以來，大部份天文學家都相信宇宙中存在著兩種黑洞，一種是由單顆恆星塌縮而成，質量比太陽大約十倍的恆星型黑洞，例如天鵝座- 1另一種是超重黑洞，這種黑洞位於星系核心，質量可達太陽數十億倍，例如我們的銀河系中心，就有一個名為人馬座a ，質量比太陽大300萬倍的黑洞。
  6. 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。
  7. 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。
  8. 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。
  9. The average range of nonthermal radiation particles is direct proportion to the energy extent of nonthermal radiation particle, but also inverse proportion to the density of stellar gas, however, to the stationary black hole with mass multipole moment and nonstationary black hole, the average range of their nonthermal radiation particle still has something to do with direction, which are the new results reported firstly

    非熱輻射粒子的平均射程與非熱輻射粒子的能量范圍成正比、與星際氣體的密度成反比；對動態黑洞和一類具有質量多極矩的穩態黑洞而言，非熱輻射粒子的平均射程還與方向有關。這些都是首次報道的新結果。
  10. In the first chapter of this paper we introduce the concept and the category of the gravitational effect before presentation of the mass - defect effect. then we simply introduce the basic knowledge in stellar and accreting theory relating to the mass - defect effect

    本文第一章中，首先介紹引力效應的概念及所屬范疇，然後引出質量虧損效應，並介紹了與這一效應相關的恆星物理學及吸積理論的基本知識。
  11. Higher mass stars will die in spectacular stellar explosions called supernovae, leaving behind even more compact objects - neutron stars for stars of mass lower than 25 solar masses and black holes for stars of mass higher than 25 solar masses

    一些質量大於8個太陽質量但少於25個太陽質量的恆星在超新星爆發后會成為中子星，而質量大於25個太陽質量的恆星最終會演化成黑洞。
  12. If that happens before the embryo has had time to attain stellar mass, the result is a brown dwarf

    假如這發生在胚胎達到恆星質量之前，結果就是一顆棕矮星。
  13. But despite their low temperatures, these quasisoft objects emitted x - ray signals that are more powerful than expected from simple neutron stars or stellar black holes. instead, the natural model for quasisoft x - ray sources is the one involving an intermediate - mass black hole

    此外，這種類軟天體溫度雖然低，但它們所發出的射線訊號較中子星和恆星型黑洞的為強，我們相信它們和中型黑洞有著密切的關系。
  14. The first is stellar - mass black holes, having a mass of a few solar masses as the name indicates. they are the end products of stellar evolution for very massive stars

    第一類稱為恆星質量黑洞，這類黑洞的質量與太陽質量的量級相若，它們都是巨大恆星演化后的最終物。
  15. The bull ' s - eye patterns seen around planetary nebulae come as a surprise to astronomers because they had no expectation that episodes of mass loss at the end of stellar lives would repeat every 1, 500 years

    這個牛眼樣的圖案出現在行星式星雲四周讓天文學家很吃驚，他們不可能期待1500年，在他們有生之年只能看到片斷。
  16. After the process of matter ejection stellar body will continue collapsing into black hole if the mass of the nuclear - energy - exhausted star is more than 3 mq

    星體經過物質拋射后，核能耗盡的恆星質量超過3m _ ，則此星體將繼續坍縮成黑洞。
  17. Candidates for stellar - mass black holes were identified mainly by the presence of accretion disks of the right size and speed, without the irregular flare - ups that are expected from disks around other compact objects

    鑒別恆星質量黑洞主要靠合適大小和速度的增大圓盤的存在，沒有認為從其它緊密物體周圍閃耀的無規律的閃光。
