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, of which a number of the talks are available here Ordinary Meeting Videos.

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.

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.

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.

Geophysical Fluid Dynamics with a Twist: in Honour of Professor Raymond Hide
Date: 30 Apr 2018
Time: 13:30

This meeting is to celebrate the memory of Raymond Hide (CBE ScD FRS) who was President of the Royal Astronomical Society, 1983-1985, and of the Royal Meteorological Society, 1974-76. The meeting will cover fundamental areas of Astronomy, Geophysics, Meteorology and Oceanography, under the broader umbrella of "Geophysical Fluid Dynamics", to which Raymond contributed so greatly.


Professor Hide had a unique approach to these areas, with a knack of drawing powerful inferences from, and connecting to reality, theoretical concepts. We intend to follow, and promote further, this spirit through the meeting with the help of speakers who have been inspired by Raymond's life and work: Prof Chris Hughes (University of Liverpool), Prof Andrew Jackson (ETH Zurich), Prof John Marshall (MIT), Prof Tim Palmer (Oxford University) and Prof Peter Read (Oxford University).


Students are encouraged to attend the meeting and can apply for financial assistance if they wish to by sending a motivation statement to Arnaud Czaja at:


Provisional Programme:

  • 1.30-1.45pm: Welcome and introduction (J. Haigh, J. Gibbon & A. Czaja --Imperial College)
  • 1.45pm-2.15pm: Prof Peter Read, Oxford University: Dynamical processes in Jupiter's atmosphere: from the laboratory to Juno and Cassini
  • 2.15-2.45pm: Prof Andrew Jackson, ETH Zurich: Fluid dynamics of the Earth's core, and the dynamo problem.
  • 2.45-3.15pm: Prof Chris Hughes, University of Liverpool: The simultaneously linear and non linear ocean.


Coffee break 3.15-3.45pm


  • 3.45-4.15: Prof Tim Palmer, Oxford University: Analogues of Potential Vorticity in Magnetohydrodynamic Fluids
  • 4.15-5pm: Prof John Marshall, MIT: Raymond Hide's influence on climate dynamics
  • 5pm: Meeting end


The Gravitational Wave Binary Black Hole Opportunity For Astronomy
Date: 11 May 2018
Time: 10:00

A RAS Specialist Discussion Meeting organised by *Carole Mundell (Bath); Samaya Nissanke (Radboud); Hiranya Peiris (UCL)


Dynamics and evolution of Earth’s coupled core-mantle system
Date: 11 May 2018
Time: 10:30

A RAS Specialist Discussion Meeting organised by Chris Davies (Leeds);
Andy Biggin (Liverpool); Dario Alfe (UCL)



Interactions between Earth's two great heat engines, the liquid core and silicate mantle, play a fundamental role in shaping the dynamics and evolution of our planet and produce potentially observable signatures that provide unique insight into the innermost workings of the core-mantle sytsem.  Recent advancements in techniques and capability are illuminating the core-mantle system in unprecedented detail and challenging established views.  This specialist discussion will focus on the big unresolved questions in deep Earth research with particular emphasis on core-mantle interactions.  Talks and posters will comprise a range of interdisciplinary topics related to this theme, including seismology, geodynamics, mineral physics, geochemistry and geo/paelomagnetism.

  • Fees: Admission to the Society's Monthly A&G (Ordinary) Meetings is open to all, at no charge. Admission to the Specialist Discussion Meetings is normally free to RAS members and £15 to non-members (£5 to students), collected on the door, while  GSL members may normally attend "G" meetings at no charge. Note that special rates apply for the February BGA meeting. RAS and GSL members should bring their membership cards, and students their student cards, as identification.
  • Tea will be served before A&G meetings (15:30, at Geological Society Lecture Theatre, Burlington House). A drinks reception will follow A&G meetings, in the Burlington House apartments of Royal Astronomical Society.
  • Coffee/registration for Specialist Discussion Meetings will commence a half-hour before the formal start time.
  • Copies of the detailed programme will be circulated, to those who have asked for them, approximately two weeks in advance of each meeting. Any member who does not already receive these details but wishes to do so should notify the Executive Director.
  • Those wishing to make a contribution at a Specialist Discussion Meeting should contact the appropriate organizers.
  • The Society welcomes suggestions for venues and topics for half- or one-day regional meetings; contact the Secretary or Executive Director.
  • Detailed notes for organizers (including the Code of Conduct for RAS meetings) are available for reference.
