Primary Star

In one such triple-star system , astronomers have just found an exoplanet . It has the rather catchy name LTT 1445Ab , as it orbits the primary star of three red dwarfs that constitute the system LTT 1445 , located around 22.5 light-years away .

在一个这样的三星系统中，天文学家刚发现了一颗系外行星。这颗星球有个很惹眼的名字：LTT1445Ab。因为它围绕着组成LTT1445系统的三颗红矮星构成的主恒星旋转，距离地球约22.5光年。

These are very unique in purpose , and differ from areas such as Titicaca , Arkansas , Grand Tetons , Shasta and Roslyn that are primary Celestial Star Gates .

在其作用上来说是有特别意义的，不同于主要作为【星际之门】的〖的的喀喀湖、阿肯色、大提顿山、沙士达山和罗斯林教堂〗这些地方。

The primary results indicate the star pattern recognition algorithm has good performance and utility value .

初步的仿真试验结果表明该星模式识别算法性能优良，具有实用价值。

As the cosmic downsizing continues , the dwarf galaxies-which hold only a few million stars each but are the most numerous type of galaxy in the universe-will become the primary hot spots of star formation .

随著宇宙持续不断地小型化，那些仅包含数百万颗恒星但却是宇宙中为数最多的矮星系，将是形成恒星的主要据点。
