RAS Meetings

The RAS holds regular monthly meetings from October to May covering all aspects of astronomy and solid-earth geophysics, planetary sciences and solar-terrestrial physics. Usually, a pair of Specialist Discussion meetings for Fellows are followed by a more general Astronomy & Geophysics ('Ordinary') meeting, open to the public.

These regular meetings are held on the second Friday of the month, normally in the RAS and Geological Society lecture theatres (both at Burlington House, London). A map to these locations can be found here, and webcasts/podcasts of a number of meetings are available.

In April, the meeting is usually subsumed into the annual week-long RAS National Astronomy Meeting (NAM). 2013 and 2014 are exceptions, as NAM has been moved to July for both those years.

E-bulletins summarising imminent meetings can be subscribed to freely.

Specialist Discussion Meetings cover all branches of astrophysics and solid-earth geophysics (including, but not limited to, cosmology, astrobiology, astrochemistry, astroparticle physics, computational astrophysics; geophysical fluid dynamics, planetary sciences, solar-terrestrial physics). If you would like to give a talk at a Specialist Discussion Meeting, please contact the Meeting Organizer.

'Astronomy & Geophysics' (A&G) meetings, also called Ordinary Meetings, have more diverse programmes of talks, at a level accessible to a general audience of scientists (and advanced amateurs).  If you would like to give a talk at an A&G Meeting, please contact the Senior Secretary.

N.B.: A&G Meetings are open to all, with free admission. Registration charges are levied for the February BGA meeting,  and for non-Fellows attending any RAS Specialist Discussion Meeting. 




Magnetic reconnection: where now and where next?
Date: 12 Dec 2014
Time: 10:30

An RAS Specialist Discussion Meeting organised by Anthony Yeates (Durham)*, Alexander Russell (Dundee), Jonathan Eastwood (Imperial)

*Contact: anthony.yeates AT durham.ac.uk

 

Magnetic reconnection is a critical process in highly-conducting plasmas ranging from the Sun's atmosphere to the Earth's magnetosphere and even laboratory experiments. It is the means by which these plasmas are able to release energy previously bound up in the magnetic connectivity. Yet despite more than a half-century of progress, researchers are still struggling with the complications of real plasmas, for example: What are the influences of kinetic effects on reconnection? How do we define and measure reconnection in three-dimensions? Can we predict where reconnection will take place in a complex magnetic field and how it will proceed? The theme of this meeting is to reflect on the cutting edge techniques and observations that are currently shedding light on reconnection, and to discuss where future efforts should be directed.

Towards gravitational wave astronomy: data analysis techniques and challenges
Date: 12 Dec 2014
Time: 10:30

An RAS Specialist Discussion Meeting organised by Matthew Pitkin (Glasgow)*, John Veitch (Birmingham) and Dr Ik Siong Heng (Glasgow)
*Contact matthew.pitkin AT glasgow.ac.uk 

 

The next few years promise to be exciting ones for the field of gravitational wave astronomy: ground-based gravitational wave detectors will begin taking data at unprecedented sensitivities; pulsar timing arrays are continuing to improve their timing accuracy; and several experiments are studying the cosmic microwave background polarisation in great detail. Together, these methods are probing a huge range of the gravitational wave spectrum, and detections will offer a wealth of new information on compact binaries, supermassive black holes, and general relativity in extreme environments from the early universe to black hole mergers. Exploiting the datasets provided by these cutting edge observations has spurred the development of novel data analysis methods to understand gravitational wave sources. This Royal Astronomical Society discussion meeting will bring together researchers from these diverse areas to encourage the sharing of techniques and foster further collaboration within the data analysis community.

RAS Ordinary Meeting
Date: 12 Dec 2014
Time: 16:00

Programme:

 

2014 RAS James Dungey Lectureship: Professor Sandra C Chapman (University of Warwick): Reconnection and Turbulence: Thinking in Pictures

 

Ask anyone about Jim Dungey and reconnection and they are more than likely to make a sketch of magnetic field topology and dynamics. Topologies, symmetries, and dynamics are often easiest to see visually, in a series of drawings of snapshots of the magnetic field and flows. However, these sketches are more than illustrative, they are pictures that follow the rules of plasma electrodynamics and as such can be used as tools to further understanding.


Both reconnection and turbulence are ubiquitous in astrophysical fields and flows. They are key mechanisms for plasma heating and particle acceleration from the energy contained in large scale plasma flows and magnetic fields. A topical question is how turbulence and reconnection are related. Does turbulence enhance reconnection? Does reconnection modify the turbulence? What are the implications for plasma heating? These processes can be observed in-situ at first hand in our solar system using satellite-borne instrumentation. We now have a rich collection of such observations and in particular, multi-point and high time resolution observations are revealing new insights into reconnection and turbulence. Alongside this, it is now becoming feasible to perform numerical simulations that capture the full non-linear physics self-consistently down to kinetic scales, in three dimensions. Testing theory and simulations with data requires us to be quantitative, under the somewhat difficult circumstances of an observed natural system. The robust, reproducible features of turbulence are statistical. Tools developed to quantify the spatial texture of fractal patterns are used to quantify the statistical similarity of fluctuations in turbulent flows.
This talk will explore the intimate relationship between topology and physics in turbulence and reconnection, and what we can learn by thinking in pictures.

Surveying the transient Universe : from electromagnetic to gravitational waves
Date: 13 Feb 2015
Time: 10:30

An RAS Specialist Discussion Meeting organised by Stephen Smartt (QUB)*, Paul O'Brien (Leicester)

*Contact: s.smartt@qub.ac.uk

 

Astronomical surveys seem poised to enter a new era when non-photonic messengers such as gravitational waves, high energy cosmic rays and neutrinos will be detected. We propose a cross-disciplinary meeting to bring together researchers working across these fields to ensure the fledgling collaborations that are springing up are given chance to blossom and to continue UK leadership. This meeting builds on a successful Royal Society meeting in 2012.
