This award will support an observational survey to detect and characterize a large sample of white dwarf stars. The goals of the project are to search for white dwarf stars in the stellar spectra obtained with the Visible Integral-field Replicable Unit Spectrograph (VIRUS) for the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), and to create population statistics to study the evolution and origin of many types of single and binary white dwarfs.The is expected to have an impact on several fields of astrophysics, including the production and evolution of white dwarfs and on the physics of matter at high densities. The project will also involve amateur astronomers and students from high school through graduate school.

该奖项将支持一项观测调查，以探测和表征白矮星的大样本。该项目的目标是在Hobby-Eberly望远镜暗能量实验(Hetdex)的可见积分场可复制单位光谱仪(VIVE)获得的恒星光谱中搜索白矮星，并创建人口统计数据来研究许多类型的单白矮星和双星白矮星的演化和起源。预计这将对天体物理学的几个领域产生影响，包括白矮星的产生和演化以及高密度物质的物理。该项目还将涉及业余天文学家和从高中到研究生院的学生。
