恒星系统

These are unevolved, slowly rotating non-active stars from a CORALIE catalogue.

这些都是来自CORALIE星表中演化稳定、低自转率、非活动性的恒星，它们已被高精度光谱仪跟踪了很长一段时间来确定其是否拥有行星系统。

This is a milestone in the search and characterisation of planetary systems around stars.

他说：这是此类研究中的一个重大事件，突出了恒星周围的行星系统。

When a star was destroyed in this manner, its entire system was ravaged by intense waves of energy and radiation capable of incinerating planets in seconds.

当恒星通过这种形式毁灭时，亦会引发它所在的整个系统被超新星爆炸释放出的强大的能量波和足以在几秒内蒸发一个行星的辐射所毁灭。

Novae occur in double star systems comprising a white dwarf - the end product of a solar-like star - and, generally, a low-mass normal star - a red dwarf.

双星系统中包含一个白矮星（类似太阳的恒星的最终演化产品）和一个红矮星。

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。

Willie Soon, geo-scientist at the Solar, Stellar and Planetary Sciences division of the Harvard-Smithsonian Center for Astrophysics in Cambridge, and Lord Christopher Monckton, chief policy adviser to the Science and Public Policy Institute in Washington DC., urge the assembled scientists to avoid the hysteria of global-warming alarmists, and instead study solar activity.

摘录：印度尼西亚国家气象局与地球物理主办国际研讨会上气候和天气的日地系统在雅加达十一月24号至26号2008.In本文博士威利不久，地质科学家在太阳能，恒星和行星科学部的哈佛大学史密森天体物理中心的剑桥，与克里斯托弗蒙克顿勋爵，首席政策顾问，科学与公共政策研究所在华盛顿特区。，敦促组装科学家以避免歇斯底里的全球气候变暖的危言耸听，而不是研究太阳活动。

Conversely, astrometry works best when a planetary system is "face-on" when seen from Earth, because then the star's movements in the orbital plane are most pronounced.

与之相反，从地球看去行星系统是&面向&的时候天体测量最有效，因为此时恒星在轨道面上的运动最显著。

Displacement of star image point and its energy distribution are analyzed.

1引言星敏感器的光学系统，将来自恒星的星光成像在CCD光敏面上，其像斑的位置和能量分布，直接关系到星点定位精度。

One theory holds that the bright star is a massive supergiant, periodically eclipsed by two tight-knit stars inside a swirling, dusty disk. The second theory holds that the bright star is in fact a dying star with a lot less mass, periodically eclipsed by just a single star inside a disk.

这两个理论，一个认为亮主星是颗超巨星，周期性地被一个由尘埃围绕的密近双星系统所掩食；而另一个认为亮主星其实是颗已经流失大量质量的垂死恒星，而尘埃云中的伴星也只有一颗。

Such massive stars tend to form in clusters, and they shed material in roiling winds that can cool down and seed planetary systems.

如此巨大的恒星一般会在星丛中生成，并通过暴风来散发内部物质，这些物质冷却并进入行星系统。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
