White Dwarf GMAT

If the incoming projectile were a white dwarf—a superdense star that packs the mass of the sun into a body a hundredth the size—the residents of Earth would be treated to quite a fireworks show.

如果接近天是一颗白矮星（whitedwarfstar，一种超密恒星，质量约等同于太阳，积却不到太阳百万分之一），那麽球上居民将可以看到一场壮丽秀。

We also describe the basic principle of white dwarf cosmochronology and its application in defining the age of the Galactic disk, globular clusters, open clusters and Galactic halo.

介绍了白矮星宇宙纪年学研究基本原理及在银盘、球状星团、疏散星团以及银晕年龄确定方面应用现状。
