Astronomy Ireland Public Lecture
The birth and death of stars
By Dr. Gareth Murphy, School of Cosmic Physics, DIAS.
Monday 14 November at 8:00pm
Trinity College, Dublin
About the Lecture
Throughout the Universe, new generations of stars are continually being born and old generations are dying. The events surrounding a star's birth are dramatically revealed by glowing waves of plasma - fast-moving jets and powerful shock waves - from behind the interstellar dust clouds in which they are born. The star's death meanwhile can lead to gigantic explosions of energy, in the form of gamma ray bursts and supernovas. For a brief time, a supernova can outshine entire galaxies! Astronomers observe from the very earliest to the latest stages of a star's life, and use the fastest Irish and European supercomputers to test our understanding: these observations and models help us understand how the Sun and planets formed, and how they will evolve.
“When shall the stars be blown about the sky, Like the sparks blown out of a smithy, and die?” - W.B. Yeats
ABOUT THE LECTURER
I was brought up in Dublin, and did a degree at UCD, followed by a PhD in Astrophysics at Trinity College Dublin. I then worked for two years in France at the Laboratory for Astrophysics in Grenoble. My research at the Dublin Institute for Advanced Studies focuses on energetic shock waves in supernova remnants, jets and gamma ray bursts. I am also interested in the rotating disks that surround young stars and their associated outflows and jets. The overall aim is to understand the driving mechanisms of shock waves and the origin of accelerated particles and radiation.
After the lecture there will be a social reception in The Lombard
and we encourage all of you to come along for a chat.
All are welcome to attend and free food will be kindly provided by The Lombard.
