项目摘要
We now know of planets numbering in the thousands. This tells us that planets are common, enough to be a usual occurrence around stars like the sun. However, despite this increasing number of planets, finding out more detail about them is difficult. What are the planets made of, and how did they form and evolve to leave the planets we see? Finding out how other solar systems formed allows us to place our own Solar System in context. Perhaps we are typical, or perhaps unique - this knowledge changes how we think about the Earth and our life upon it.One way to study how other planets form is to look at their cores. The planetary core shows the environment it began in, with its composition telling us what materials were present at its beginning, before it obtained an envelope of gas. We still do not know any great detail about the cores of Jupiter and Saturn, because their gas envelopes block the core from view, and the same is true of other worlds. But planets close to their host star receive a lot of light and energy, enough to evaporate the gas and reveal the core. By uncovering a new population of these planets, I want to find out the dominant composition of their cores, discovering if they formed differently from others. As such short period planets do not exist in the Solar System, I will be uncovering the evidence of a new type of planetary evolution and history.
我们现在知道行星的数量有几千个。这告诉我们,行星是常见的,足以成为像太阳这样的恒星周围的常见现象。然而,尽管行星的数量越来越多,但要了解更多关于它们的细节是困难的。行星是由什么组成的,它们是如何形成和进化到我们所看到的行星的?了解其他太阳系是如何形成的,使我们能够将我们自己的太阳系置于背景中。也许我们是典型的,也许是独一无二的--这一知识改变了我们对地球和我们在上面生活的看法。研究其他行星如何形成的一种方法是观察它们的核心。行星核心显示了它开始时的环境,它的成分告诉我们在它获得气体包层之前,它开始时存在什么物质。我们仍然不知道木星和土星核心的任何细节,因为它们的气体外壳挡住了核心的视线,其他世界也是如此。但是靠近其宿主星星的行星接收到大量的光和能量,足以蒸发气体并露出核心。通过发现这些行星的新种群,我想找出它们核心的主要成分,发现它们的形成是否与其他行星不同。由于太阳系中不存在这样的短周期行星,我将揭示一种新型行星演化和历史的证据。
