Sungrazing Comets - Falling Into Hell
by Professor Alan Fitzsimmons, Queens University Belfast.
February 13th 2017
Venue: Physics Building Trinity College Dublin
We are extremely honoured to be hosting our February lecture with Prof. Alan Fitzsimmons, QUB. Prof. Fitzsimmons is a world class speaker who is a regular on every National Geographic, Discovery Channel, & BBC documentary about Comets. We are absolutely delighted that he has agreed to give us a Public Lecture and we urge you all to see why he is in such demand with the world's best documentary makers.
Our contact number is 086 06 46 555 during office hours. We apologise in advance for any inconvenience caused should you have any difficulties.
About the Lecture
Many people are familiar with the idea of comets being icy visitors from the outer Solar system. The Sun's heat allows the releases of gas and dust from the comet, forming the coma and tails which look so impressive in images. Many comets either orbit the Sun regularly, or go around the Sun once never to return in a single lifetime (if at all). But most comets are in fact spotted on kamikaze dives towards the very edge of the Sun, to be vaporised in a final blaze of glory. This talk will explain how these comets are discovered, how we are starting to understand their nature, and what happens to them as they fall into their personal hells.
About the Lecturer
I am an astronomer in the QUB Astrophysics Research Centre and a member of the Solar System Group . My primary research interests are in performing observations of minor bodies in our solar system, comets and asteroids. These studies are generally based on observations performed on the UK supported telescopes in the Canary Islands ( ING ) and Chile ( ESO ), although for the past few years I've been looking at the firehose of data from Pan-STARRS 1 . For an idea of what these telescopes look like, here's a picture of me standing nervously under the ESO Very Large Telescope .
My official University stats page is here , but in summary I am a currently a member of the following current projects:
- UK Pan-STARRS Science Consortium - finding lots of NEOs, asteroids and comets
- UK LSST Consortium - we will find lots of NEOs and other stuff
- NEOShield-2 Project - proposing how to move an asteroid, you know, just in case...
- The Rosetta ground-based observations team - following Rosetta and comet 67P/Churyumov-Gerasimenko all around the Sun
- ISSI Near-Sun Comet Team -what are the properties of Sungrazing and Sunskirting comets, and how do they interact with the solar corona?
- ISSI Main-Belt Comet Team -ices in the asteroid belt.
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.
