ABOUT THE LECTURE

This lecture will be presented on the ZOOM platform in line with Public Health Guidelines.

With new facilities such as the James Webb Space Telescope we may soon have the first observations of the earliest stars, but to understand these observations we will require detailed simulations.

The first stars were very different to stars that we see today, they were more massive, much hotter and only contained elements formed during the Big Bang, meaning that they would have evolved very differently, and produced more black holes and explosive events. Using stellar evolution modelling, we investigate these first stars for a range of masses up to 120 times the mass of the sun, both rotating and non-rotating.

This research sheds new light on the behaviour of the first stars and how they may have impacted their surroundings, particularly in relation to their final fates.


ABOUT THE SPEAKER

 

 

 

Laura Murphy is a PhD student in the School of Physics in Trinity College Dublin studying the first stellar explosions and their progenitors.

Laura was awarded the Irish Research Council postgraduate research award in 2017 to fund her research. She is a member of the Supernovae and Stellar Evolution research group led by Professor Jose Groh. Her work aims to understand the nature of the first stars and their explosive deaths as supernovae, with particular emphasis on how rotation affects their evolution.
