Studies of White Dwarfs and Related Objects

将测量接近白矮星演化阶段的白矮星和恒星的有效温度、表面引力、光度和质量。这些参数将允许测试白矮星的内部结构，允许更好地解释对这些恒星的X射线和紫外线观测，并测试我们对这些恒星中物理过程的理解。对热矮星的类似观测将得出此类恒星的空间密度。将对微弱的红色主序星进行观测，以获得基本参数并确定恒星的质量下限。还将分析色球活动和最低质量恒星的动力学性质。

The effective temperatures, surface gravities, luminosities and masses of white dwarfs and stars which are approaching the white dwarf stage of evolution will be measured. These parameters will permit tests of the interior structure of white dwarfs, allow better interpretation of x-ray and ultraviolet observations of these stars and test our understanding of physical processes in these stars. Similar observations of hot subdwarfs will yield space densities for such stars. Faint, red main sequence stars will be observed to obtain basic parameters and determine the lower mass limit for stars. Chromospheric activity and the dynamical properties of the lowest mass stars will also be analyzed.
