  7. Because the photospheric temperature of carbon stars are less than 3000k and the temperature of rich - dust envelope formed by the mass loss is lower, and therefore most of the energy from carbon stars are radiated between 1 to 60um range, in which the vibrational and ro - vibrational bands of many molecules also lies, the study of infrared spectra in this wavelength range is very important to reveal chemical compositions, dust formation process, the atmospheric structure and evolutionary status of stars

    碳星光球的有效溫度不超過3000k ，同時較大的質量損失率形成了富碳的塵埃殼層，以致於它的輻射能量主要集中在1 ? 60 m的紅外波段上，並且許多分子的轉動振動能譜也集中在紅外，因此在紅外波段的研究對揭示碳星化學成份及其分佈、塵埃形成過程、恆星大氣結構和演化狀態都有十分重要的意義。

  9. 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。
  10. 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。
  11. The temperature a star attains is determined by its mass.

    恆星所達到的溫度取決於它的質量。
  12. Because of its great mass, both the core temperature and density are higher than that of a solar mass star. the nuclear reaction rate is also higher and it produces more energy per second. the star is of spectral type o, b or a

  13. Which will eventually form stars of spectral types g, k or m. t tauri stars are surrounded by a huge cloud and they are very young, with low surface temperature. they emit most of their light in the infrared region and they appear red. a general principle is, a violent reaction will give out short wavelength waves, like gamma rays or x - rays ; while a gentle process will radiate long wavelength waves, like radio or infrared

    ，這類星最後會演化為g k或m型恆星，金牛座t型星為表面溫度低而非常年青的恆星，四周被星雲所圍繞，所以這種星顏色偏紅，較容易在紅外線波段找到一個普遍的原則是，如果活動越激烈，則所放出的光波波長越短，主要會為伽瑪或x射線如果活動溫和，則會發放出如無線電波或紅外線等長波長電磁波。
  14. 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。

  16. Is the most important diagram in discussing stellar evolution. it is a plot of the surface temperature versus the brightness or luminosity of stars

    是研究恆星演化最重要的工具，它顯示了恆星表面溫度和恆星光度的關系。
  17. These two types of stars are so hot that most of their lights are emitted in the ultraviolet region

    這兩類恆星由於表面溫度太高，所發出的光大部分屬紫外光。
  18. Stars are classified by their spectral lines well before we know that those lines are also related to the temperature. the classes of spectral lines are called the

    早在科學家了解顏色和溫度的關系之前，天文學家早已根據光譜的吸收線把恆星分類，這種分類方式稱為
  19. If it is hotter, it is yellow, etc. thus, we could tell the surface temperature of a star by its color

    因此，我們可以根據恆星的顏色，得知它的表面溫度。
  20. Therefore, the color of a star is mainly determined by its surface temperature, but its luminosity is determined both by its surface temperature and the surface area

    所以，恆星的顏色由表面溫度所決定，而恆星的光度則由表面溫度和表面面積所決定。
