IAA Zoom Meeting Weds Dec 8th – Dr Jamie Robinson

“Asteroids: the key to unlocking the secrets of the Solar System ”

Synopsis

Asteroids are the small bodies of the Solar System which represent the leftovers of planet formation. They can be found throughout the Solar system, mainly in the rocky asteroid belt between the orbits of Mars and Jupiter and the more icy region beyond the orbit of Neptune.


By considering the physical properties of these bodies and how they came to be on their present orbits one can investigate the various processes of Solar System formation. Asteroids provide clues as to how the first solid bodies grew out of the disk of gas and dust from which the Sun was born, and how these small bodies then grew into the major planets. Furthermore their distribution throughout space tells us how the planets would have migrated from their birth locations in the early Solar System, scattering these asteroids as they went.


The asteroids are an invaluable key to unlocking the secrets of the Solar System, helping to explain how planets such as the Earth came to be. They are both the building blocks of our planet from which life developed and also a threat to life in terms of their continuing collisions with the Earth. As such they are fundamentally linked to understanding our place in the Universe and are an extremely fruitful subject of study.

James (Jamie) Robinson

2011 – 2016: MPhys Durham University (year abroad at McMaster University 2013 – 2014)
2016 – 2020: PhD at Queen’s University Belfast on The Origin and Evolution of Transneptunian Binaries. 2017 LSST Data Science Fellow
2020 – 2021: Postdoc at QUB, ATLAS asteroid science
2021 – present: Postdoc at University of Edinburgh, LSST software tools

My research has covered a wide range of topics within the realm of small Solar System bodies. These objects represent the leftovers of planet formation and have a diverse range of physical and orbital properties. My research makes use of intensive computations and data science techniques to simulate and investigate the properties of small Solar System bodies. Studying such objects provides a valuable constraint on how the Solar System formed and gives us insight into how the Earth, and life, came to be.


For my PhD I conducted intensive numerical simulations to study how a binary pair of planetesimals can form through the collapse of a cloud of pebbles in the outer reaches of the early Solar System. I also considered how such binaries evolved under the effects of planetary migration which is believed to produce the Solar System of today.


I then took up a postdoctoral position at QUB which brought my research into the inner Solar System. I have utilised the large database of photometry from the ATLAS survey to study the surface properties of asteroids. The Asteroid Terrestrial-impact Last Alert System is one of several wide field surveys that scan the sky discovering transient phenomena and I assist in efforts to analyse the data in real time searching for possible Earth impactors.


I have recently started a postdoc at the University of Edinburgh where I will focus on developing software tools for the next big wide field survey, the Legacy Survey of Space and Time. LSST will be a revolution in Solar System science, discovering and characterising an order of magnitude more objects than previously known.

IAA Zoom Lecture 10th Nov 19:30 – Dr. Donnacha O’Driscoll (IAS)

“Earth’s Constant Companion”

Synopsis.

This will be a general presentation on Earth’s constant celestial companion, the Moon. Its formation, physical attributes, movements, effects on the Earth and how to observe it. It will be a fun, entertaining and hopefully informative talk that will have something in it for all ages with no prior knowledge required

Biography

It is presented by IAS member Dr. Donnacha O’Driscoll who is a scientist by profession. He is the General Manager of the Science Foundation Ireland research centre ‘Insight’ in UCD.

Although professionally he has worked in the biotechnology and data analytical sectors, his passion is in astronomy and in particular Lunar astronomy.

He has been an active observer of the Moon for over 40 years and has presented many talks on the subject in that time. He established and runs the website www.themoon.ie which is an outreach project, acting as a source of information and teaching aids on all things Lunar to individuals young and old and to various groups and schools.

International Observe the Moon Night, Sat 16th October, at Delamont Country Park

Note This event is cancelled due to poor weather

Near Killyleagh, Co Down, 7.30 p.m.

54.384, -5.677

https://goo.gl/maps/gBHCfJXcJtH9QMhY9

Meet in the main car park. We will provide some telescopes, but bring your own, or binoculars, if you can. We will be providing sanitising wipes for eyepieces and hand controls etc, and these will be wiped clean between users. We strongly advise that only those who are double-vaccinated, or who have had Covid and recovered and with at least one vaccination, should attend.

We will take phone numbers of all groups attending, anyone bringing a telescope will also need to bring a pack of antibacterial wipes, and wipe eyepiece cups and focuser knobs for each viewer, and all telescope operators to wear a mask at close quarters etc.

We will be introducing more Observing nights – see this page for dates. The Covid Pandemic isn’t over so we will need to follow precautions as outlined above to keep us all as safe as possible.

IAA Lecture, Weds 13th October 19:30

“Habitability beyond our solar system”, by Professor Chris Watson

Deputy Head of the School of Mathematics and Physics, Astrophysics Research Centre, QUB

Synopsis:

What do we mean by ‘habitability’ and ‘habitable’? How do we define it? Do we even know what ‘habitable’ looks like? What’s the problems with determining whether something is habitable? Why are we looking in the places we’re currently looking? Actually, are we even looking in the right places?

 I’ll talk about the current scientific thoughts surrounding these fundamental questions, what is driving these thoughts, and why it’s so difficult for an astrophysicist like myself to answer these questions.
