Globular Clusters, Stellar Collisions, Dark Matter Halos, and the Age of the Universe Problem

Bolte博士的观察研究项目解决了四个问题：1)银河系中最古老的球状星团的绝对年龄，2)银河系球状星团之间以及与银河系伴星的矮球状星系之间的年龄弥散，3)星族II恒星质量/光度函数的低质量端，4)球状星团中蓝离散星的性质及其发生频率与单个星团内和不同星团内恒星密度和速度色散的关系。

9420204 Bolte Dr. Bolte's observational research project addresses four problems: 1) the absolute age of the oldest globular star clusters in the Galaxy, 2) the age dispersion among the galactic globular clusters and for the dwarf spheroidal galaxies that are companions to the Milky Way, 3) the low-mass end of the Population II star mass/luminosity function, and 4) the nature of blue straggler stars in globular clusters and the frequency of their occurrence as a function of stellar density and velocity dispersion within the individual clusters and for different clusters.
