恒星

If there were in fact rocky planets within the inner gap between the star and asteroid belt, the worlds would likely reside within the star's habitable zone where temperatures would be such that life could survive.

如果在恒星和小行星带之间的内围间隙中确实存在岩石行星，那么这些星球可能会位于这颗恒星的可居住带上，其温度可能会适于生命生存。

He conceived of a space time continuum that is curved by mass; in other words, planets, stars, galaxies and other stellar objects cause a curvature of space time.

他的构想是一个时空连续弯的质量；换句话说，行星、恒星、恒星和星系等物体造成时空曲率。

The researchers detected hydrogen cyanide molecules in disks circling yellow stars like our sun -- but found none around cooler and smaller stars, such as the reddish-colored "M-dwarfs" and "brown dwarfs" common throughout the universe.

研究人员在类似太阳的黄色恒星周围的星云盘中检测到了HCN，但在更冷更小的恒星——比如遍布宇宙的M型红矮星和棕矮星——周围却没有找到HCN踪迹。

Sidereal month, the moon in the celestial sphere on two consecutive pass C had a stellar time interval, the length of 2732166 level solar day. C (5) calendar month, a calendar year is divided into 122 months, 1,3,5,7,8,10, and December 31 each for flat solar day, 4,6,9 and 11 month for 30 a flat solar day, in February for the 28 flat solar days, a leap year for the 29 level solar day.

恒星月，月球在天球上连续两次通C过某一恒星所需的时间间隔，长度为2732166平太阳日。C（5）公历月，一公历年分为122个月，1、3、5、7、8、10和十二月各为31个平太阳日，4、6、9和11月各为30个平太阳日，2月份为28个平太阳日，闰年为29个平太阳日。

So he compiled data on more than 20,000 stars from existing sky surveys whose position in our galaxy and orbital velocity had been accurately measured.

这样，他从现有的天空观测资料中搜集到20，000多颗恒星的资料。这些恒星都位于我们银河系，对它们的轨道速度已经有过精确地测量。

Another method, called microlensing--in which a planet's gravity momentarily brightens a background star by bending its passing light--is particularly good for detecting planets more distant from their stars and in principle could spot lightweights with masses down to that of Earth.

另一种方法即所谓的透镜--其中一颗行星的引力通过弯曲经过的光线瞬间增亮背后的恒星—-对于探测距离恒星更遥远的行星是特别好的，并且在原则上可以透过降落到地球上的物质发现轻量级的行星。

The metallicity excess could result from either the accretion of planets/planetesimals on to the star or the protostellar molecular cloud.

含金属过多是由行星/行星原质或原始恒星分子云的吸积引起的。同时，这种过金属性质也表现在类太阳&有行星&恒星中（参见图表2c）。

By observing the Doppler shifts of stars moving near the galactic plane, Oort was able to calculate how fast the stars were moving.

借助观察靠近银河面的运动恒星多普勒变换，Oort能够计算出恒星移动多快。

借助观察*近银河面的运动恒星多普勒变换，Oort能够计算出恒星移动多快。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
