The effects of dynamical interactions in star clusters on planetary systems

大多数恒星形成在密集的群体中，与其他恒星的相互作用是常见的。此外，行星与恒星同时形成，因此星星经历的任何动力学相互作用都可能影响行星的形成。在这个博士学位，艾玛达弗恩鲍威尔是模拟恒星相互作用对初出茅庐的行星系统的影响。她将开始确定太阳系是否可以从另一颗星星捕获一颗行星，然后再研究恒星形成环境对行星种群的一般影响。艾玛然后将研究双星对行星的影响，其中扰动效应来自恒星伴侣以及经过的恒星。

Most stars form in dense groups where interactions with other stars are common. Furthermore, planets form at the same time as stars, and so any dynamical interaction a star undergoes is likely to affect planet formation. In this PhD, Emma Daffern-Powell is simulating the effects of stellar interactions on fledgling planetary systems. She will begin by determining whether the Solar System can capture a planet from another star, before looking at the general effects of the star-formation environment on a population of planets. Emma will then look at the effects of binary stars on planets, where the perturbative effects come from the stellar companion as well as passing stars.
