The numbers of white dwarfs at different brightnesses and colours maps out a continuous record of the star formation history of the Milky Way. Our program seeks to unravel that history using white dwarfs discovered with the SkyMapper Survey and thereby understand how our Milky Way galaxy and other galaxies evolved the form and mixture of sub-structures that we see today. These results will be widely disseminated stimulating interest in the natural sciences amongst the general public and the nation's youth. We will train young researchers in cutting edge science, enhancing skills in data analysis, stellar atmosphere and interior computations and problem solving.

不同亮度和颜色的白矮星的数量描绘出银河系恒星形成历史的连续记录。我们的计划试图用SkyMapper Survey发现的白矮星来揭开那段历史，从而了解我们的银河系和其他星系是如何演变成我们今天看到的亚结构的形式和混合的。这些成果将广泛传播，激发公众和全国青年对自然科学的兴趣。我们将培养尖端科学方面的年轻研究人员，提高数据分析、恒星大气和内部计算以及解决问题的技能。
