This project will use the all sky survey TESS data to create a statistically robust sample of planets with measured radii and masses, and hence inferred densities. The TESS data will allow statistics on planet size distribution to be calculated, but due to its bright target selection enough of these detections should be characterisable by radial velocity to lead to a standardisable sample of planet masses and densities. The results will allow a deep understanding of the typical composition of planets, what level of core and envelope mass fractions are typical, and provide experimental constraints on planet structure and formation models.

这个项目将使用全天巡天TESS数据来创建一个统计上可靠的行星样本，通过测量的半径和质量，从而推断出密度。TESS数据将允许计算行星大小分布的统计数据，但由于其明亮的目标选择，足够多的这些探测应该是径向速度的特征，以导致行星质量和密度的标准禁用样本。这些结果将使我们能够深入了解行星的典型组成，核心和包层质量分数的典型水平，并为行星结构和形成模型提供实验约束。
