This dust reddens the starlight in many places, just like a dusty atmosphere reddens the sunset.
这些尘埃,使得那些恒星的光看起来变红,就像在日落时那些满是灰尘的大气将太阳光散射,使之看起来变红了。

Furthermore, Binary stars have been neglected in most studies of the integrated light of the stellar populations with the EPS methods. However in real clusters and galaxies over 50% stars are in binaries, and binary interaction can result in some important classes of objects, such as blue straggles and subdwarf B stars (sdB, also referred as extreme horizontal branch ) which contribute significantly to the integrated light.
另外,多数演化星族合成模型在对星族进行研究时没有考虑双星作用,而在真实星团或星系中50%以上的恒星属于双星系统,双星相互作用可以产生一些重要天体,例如蓝离散星和B型亚矮星,而这类天体对积分光谱有重要影响,因此本论文研究目的之二就是在演化星族合成模型中考虑双星作用。

Orbiting a Red Dwarf Star Image of the Day Gallery Orbiting a Red Dwarf Star This artist's concept of a gas giant planet orbiting a red dwarf K star shows a planet has not been directly imaged , but its presence was detected in 2003 microlensing observations of a field star in our galaxy .
此图本意是拍摄一颗环绕红矮星K运行的由气体组成的巨大行星,但并未直接对其成像,不过该行星的踪迹在2003年针对银河系中恒星带的引力透镜现象进行观测时被发现。

"Studying Epsilon Eridani is like having a time machine to look at our solar system when it was young," said researcher Massimo Marengo, an astronomer at the Harvard-Smithsonian Center for Astrophysics in Massachusetts.
&研究恒星' E 波江'就象有了一台时间机器,可以用来观察我们太阳系年轻时的情形,&研究人员马西莫·马伦果说。马伦果是马萨诸塞州哈佛-史密森天体物理中心的一位天文学家。

If the star is moving towards us its spectrum is blueshifted, and redshifted correspondingly when it moves away from us.
当恒星向我们运动时,其光谱将蓝移;反之将红移。

But this well-studied example of a planetary nebula, produced near the end of the life of a sun-like star, is now understood to have a surprisingly complex geometry.
但事实并非如此。螺旋星云事实上已经是已被广泛研究的行星状星云的很好的例子。它是类太阳恒星在寿终时所演变成的。

To work out how massive it was, they recorded the motion of the star as it was tugged on by the orbiting planet.
通过计算行星掠过时恒星光线粒子的规模,可以计算出这个行星的半径大小。

"The material mix in this belt is most reminiscent of the stuff found in lava flows on Earth," Lisse said. I thought of Mauna Kea material when I first saw the dust composition in this system - it contains raw rock and it's abundant in iron sulfides , which are similar to fool's gold .
& &这个尘埃巨带中的混合物质使人想到地球上熔岩流中发现的物质,&利斯说,&第一次看见这个恒星系统中尘埃的组成成分时,我想起了夏威夷莫纳克亚山上的物质——其中包含原岩,富有含铁硫化物,类似于黄铁矿。
