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.

如果接近的天体是一颗白矮（whitedwarfstar，一种超，质量约等同于太阳，但其体积却不到太阳的百万分之一），那麽球上的居民将可以看到一场壮丽的烟火秀。

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.

介绍了白矮宇学研究的基本原理及其在银盘、球状团、疏散团以及银晕龄确定方面的应用现状。
