On the other hand, einstein discovered that the maximum velocity of any object is the speed of light. therefore, if the escape velocity on the surface of an object is greater than the speed of light, then nothing, including light, can escape from it
另一方面,愛恩斯坦的相對論斷言宇宙中最高的速度便是光速,所以如所需的逃逸速度大於光速,那麼宇宙中包括光在內的一切都不可能逃離引力的魔掌,這顆恆星便成為To search for high - velocity molecular emission toward massive star formation regions, and to study the connections between h2o masers, iras objects and outflow properties, we carried out a co observation for a h2o maser sample. we found that most of the objects have excess high velocity emission produced by outflows ; we find a significant correlation between co line full widths and iras luminosities. the widths are proportional to the iras luminosities
通過在大質量恆星形成區搜尋高速分子輻射,並且研究它們與星際h _ 2o脈澤源和所聯系的紅外源之間的關系,我們發現絕大多數源都存在著氣體的高速運動並且它們是由分子外流產生的;我們同時發現在co分子的譜線全寬和所對應源的紅外光度之間存在很好的相關性,線寬隨紅外光度增加而變大。Even with spitzer ' s highly sensitive spectrometer, isolating the light coming from a dim planet orbiting in the immediate vicinity of a bright star is a daunting challenge
即便有「斯必擇」高度靈敏的光譜儀,要分離出一個十分靠近明亮恆星的行星暗淡的光也是令人畏懼的挑戰。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
由於質量更大,恆星核心的密度及溫度亦必然比小質量恆星高,所以熱核反應會以更快速度進行,產生出更多的熱能,恆星會更加光亮,這些恆星通常為o b或a型恆星。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。分享友人
