The WASP survey has discovered hundreds of solar-type stars with low mass stellar companions (M-dwarfs) as a by-product of its highly successful search for transiting exoplanet systems. Extensive spectroscopic follow-up of these objects has been obtained by our collaborators. The aim of the project is to use these data and other follow-up observations to study the properties of low mass stars. This first task in the project will be to develop an automated method to determine the properties of the solar-type star from its spectrum using wavelets to optimise the information that can be extracted from the spectra.

WASP调查发现了数百颗太阳型恒星，它们的低质量恒星伴侣（M矮星）是其非常成功地寻找凌日系外行星系统的副产品。我们的合作者对这些天体进行了广泛的光谱跟踪。该项目的目的是利用这些数据和其他后续观测来研究低质量恒星的性质。该项目的第一项任务将是开发一种自动化方法，利用小波优化从光谱中提取的信息，从光谱中确定太阳型星星的属性。
