RUI: White Dwarf Stars in Wide Binary Systems: Physical Parameters and Comparisons to Single Degenerates

奥斯瓦尔特和他的合作者锡永将获得白色的光谱 为了确定它们的质量， 它们的进化历史，以及识别新的白色矮星， 特别是那些不寻常的阶级。 白色矮星是地球大小的恒星， 在耗尽所有核燃料后， 最近 观察已经证明了令人惊讶的许多种 白色矮星的大气层。 Oswalt和锡永会用 几百颗白色矮星来确定它们的质量。 这些基本参数提供了恒星 最初很像太阳， 而不像是一组白色矮星。 奥斯瓦尔特和锡永还希望 来识别更多的白色矮星，这样就可以发现更多不寻常的种类， 可以更好地研究。 该奖项是根据研究在 本科院校计划。 提供部分支持 通过本科生项目的研究经验。

Oswalt and his collaborator Sion will obtain spectra of white dwarfs in order to determine their masses, to learn more about their evolutionary histories, and to recognize new white dwarfs, especially those of unusual classes. White dwarfs are Earth-sized stars, the final state of stars like the Sun after they have exhausted all nuclear fuels. Recent observations have demonstrated surprisingly many kinds of atmospheres on white dwarfs. Oswalt and Sion will take spectra of several hundred white dwarfs in order to determine their masses. These fundamental parameters provide information how stars originally rather like the Sun end up as members of apparently rather unlike sets of white dwarfs. Oswalt and Sion also expect to identify many more white dwarfs, so that the more unusual kinds can be studied better. This award is made under the Research in Undergraduate Institutions Program.
