Stars & Planets on the run.

Guest Speaker

Thursday, 13th August 2020 (19:45 - 22:00)

Venue: Virtual Meeting

Most stars form in grouped or clustered environments with other stars. These stars-forming regions can survive millions of years, but can change dramatically over just a short period of time - either collapsing under their own gravity or expanding. So what we see today might not be what they looked like initially when they formed. While a cluster is contracting or expanding, stars can pass very close to each other. This can lead to stars being flung out of the cluster to become runaway stars, as well as planets being ejected from their orbits and even swapped between stars. In this talk we will discuss how simulations and observations are used to investigate these interactions in young star-forming regions.

 

Christina will talk about how the number and distribution of runaway stars can tell us something about the initial conditions of these regions. And how observations from telescopes like Gaia, which orbits in space with the Earth around the Sun, can be used to search for these ejected stars in the night sky. Emma will talk about how close encounters with other stars can affect exoplanets, as well as how this is relevant to our own Solar System.

Speaker: Dr. Emma Daffern & Dr Christina Schoettler
