恒星

At the dimmest part of a Cepheid's cycle, the ionized gas in the outer layers of the star is opaque, and so is heated by the star's radiation, and due to the increased temperature, begins to expand.

在造父变星的一个光变周期开始时，恒星最暗，此时其外层电离气体是相对不透明的，因此会吸收恒星的辐射而升温，并开始向外膨胀。

The various colours significant of various degrees of vitality (white, yellow, crimson, vermilion, cinnabar): their degrees of brilliancy: their magnitudes revealed up to and including the 7th: their positions: the waggoner's star: Walsingham way: the chariot of David: the annular cinctures of Saturn: the condensation of spiral nebulae into suns: the interdependent gyrations of double suns: the independent synchronous discoveries of Galileo, Simon Marius, Piazzi, Le Verrier, Herschel, Galle: the systematisations attempted by Bode and Kepler of cubes of distances and squares of times of revolution: the almost infinite compressibility of hirsute comets and their vast elliptical egressive and reentrant orbits from perihelion to aphelion: the sidereal origin of meteoric stones: the Libyan floods on Mars about the period of the birth of the younger astroscopist: the annual recurrence of meteoric showers about the period of the feast of S.

To Louis's goggled eyes, the sun, twelve million miles distant, was a blurred rim of flame around a wide, solid black disc.

透过眼镜，路易斯看到，恒星——那颗一千二百万英里之外的恒星，变成了庞大的黑色圆盘，其外缘有模糊的光晕。

"If you look at how the spectrum of the star changes when the planet transits across it, you can work out which way the planet is travelling," Professor Hellier added.

英国科学家利用一系列观测恒星的照相机进行观察恒星发出的光线粒子时，这颗行星在他们面前掠过，这才发现了这颗行星。

Scientists have no way of knowing whether life ever existed on any comets or planets orbiting this particular star, known as CW Leonis and located some 3,000 trillion miles (4, 800 trillion kilometers) from Earth in the constellation Leo.

科学家还无法知道在这颗恒星周围运行的彗星和行星上是否曾经有生命存在。该恒星是狮子座的CW星，距地球大约3000万亿英里(4800万亿公里)。

该恒星是狮子座的CW星，距地球大约3000万亿英里（4800万亿公里），科学家还无法知道在这颗恒星周围运行的彗星和行星上是否曾经有生命存在。

We now discuss the impact of age and metallicity on the Li abundance of solar analogue stars.

现在我们主要讨论的是：&类太阳&恒星中，与锂含量有关的恒星年龄和金属性效应问题。

The correlations of the specific star formation rate with stellar mass and metallicity are found.

发现星系的特征恒星形成率与恒星质量和金属丰度之间存在着显著的相关性。

These stars formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula's center, insulated by a layer of dust and hot gas.

在大约4百万年前，这些恒星从它周围的星云物质中形成的。它们所发出的恒星风在星云的中心挖出一个空洞，而空洞的边缘有一层由尘埃和炽热气的隔离层。

These stars formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula's center, insulated by a layer of dust and hot gas.

在四百万年以前，星云物质聚集形成了这些恒星，它们的星风（一种从恒星不断向外运动的物质流，类似于太阳风）在星云中央清理出了一个空洞，这个空洞被一层尘埃和灼热气体所包围隔绝。

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.
