Collaborative Project: Periodic Phenomena in Cataclysmic Binaries

我们对灾难性双星的轨道演化、旋转、光度波和发射线行为的理解取决于对它们亮度和光谱的周期性变化的观测。不幸的是，很少有系统的努力来测量这些周期性，并将光度行为与光谱行为联系起来。PI将与达特茅斯学院的J. Thorstensen合作解决这个问题。PI将获得大量的光度数据，而Thorstensen将收集许多灾难性双星的光谱。＊＊＊

9314567 Patterson Our understanding of the orbital evolution, rotation, photometric waves and emission line behavior in cataclysmic binary stars hinges on observations of periodic variations in their brightnesses and spectra. Unfortunately, there has been little systematic effort made to measure these periodicities and link the photometric behavior with the spectroscopic behavior. The PI will collaborate with J. Thorstensen of Dartmouth College to address this shortcoming. The PI will obtain large amounts of photometric data while Thorstensen will collect spectra for many cataclysmic binaries. ***
