The effects of dynamical interactions in star clusters on planetary systems

大多数恒星形成密集的星团，在那里与其他恒星的相互作用很常见。此外，行星与恒星同时形成，因此恒星发生的任何动力学相互作用都可能影响行星的形成。在这篇博士论文中，Emma Daffern-Powell正在模拟恒星相互作用对羽翼未丰的行星系统的影响。她将首先确定太阳系是否能从另一颗恒星上捕获一颗行星，然后再研究恒星形成环境对行星数量的总体影响。然后，Emma将研究双星对行星的影响，其中微扰效应来自恒星伴星和过往恒星。

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.
