My research focuses on exoplanet discovery using the radial velocity method, specifically around binary star systems. Binary systems will affect their surrounding protoplanetary disk providing an alternate planetary formation path than single star systems, thus revealing which may be more common. Only a few of these "circumbinary" planets have been discovered so far, with many more expected to exist. Finding these planets could reveal vital information on the formation and evolution of planetary systems. Which could in turn provide us with a better idea as to how our own Solar system formed. This research will utilise data collected by telescopes such as the High Accuracy Radial velocity Planet Searcher (HARPS) a spectrograph located at the La Silla Observatory in Chile, and from the SOPHIE spectrograph, mounted on the 1.93m at the Observatoire de Haute-Provence, in France.

我的研究主要集中在使用径向速度方法发现系外行星，特别是在双星星系统周围。双星系统将影响其周围的原行星盘，提供一个替代的行星形成路径比单星星系统，从而揭示哪一个可能更常见。到目前为止，只有少数这些“环联星”行星被发现，预计还有更多的行星存在。找到这些行星可以揭示行星系统形成和演化的重要信息。这反过来又能让我们更好地了解我们自己的太阳系是如何形成的。这项研究将利用望远镜收集的数据，如位于智利拉西拉天文台的高精度径向速度行星搜索器（HARPS）光谱仪，以及安装在法国上普罗旺斯天文台1.93米处的SOPHIE光谱仪。
