This project aims to determine the detailed properties of "sub-Saturn" planets. Theories of planet formation are heavily biased toward explaining our Solar System, which is not representative of the general population of planetary systems in our Galaxy. The vast majority of other planetary systems feature “warm sub-Saturns”: planets of ~10-100 Earth masses orbiting close to their host star. Due to a shortage of well-characterised sub-Saturns, little is known about their composition and detailed properties. This project aims to advance our understanding of planet formation via intensive, dedicated ground-based characterisation of these new planets.

该项目旨在确定“亚土星”行星的详细性质。行星形成的理论严重偏向于解释我们的太阳系，而太阳系并不能代表我们银河系中行星系统的总体数量。绝大多数其他行星系统的特点是“温暖的亚土星”：质量约为10-100个地球质量的行星围绕着它们的主恒星运行。由于缺乏特征良好的亚土星，人们对它们的组成和详细性质知之甚少。该项目旨在通过对这些新行星的密集、专注的地面特征来促进我们对行星形成的理解。
