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.
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.

The emergence of classical behaviour from a quantum background is crucial to understanding the formation of structures in our universe and deserves serious investigation, but the passage from quantum fluctuations to large scale structure in the universe is poorly understood. Because this problem, like the fine-tuning problems mentioned above, combines questions in small scale quantum physics with questions in large scale gravitational physics, coming to grips with it requires input from both fields.
By bringing together classical and quantum cosmology we will shed light on the fundamental issues involved in applying quantum physics to cosmology as well as understanding how probabilistic quantum predications can lead to a well-defined set of cosmological parameters—parameters to which the standard model of cosmology is highly sensitive. We will examine whether the sensitivity of our models on these parameters shows our world—or models—to be fine-tuned, and whether the physics of our local universe blurs this sensitivity, rendering the emergence of structure, and life, even more unlikely in the cosmological context.

Making Britain: evidence for catastrophic flooding in the English Channel
It has been previously suggested that the separation of Britain from mainland Europe in the late Quaternary was a consequence of a catastrophic flood caused by a spillover of a proglacial lake that occupied the present-day southern North Sea basin during the Elsterian glaciation. Such an event would have significant palaeogeographic, biological and archaeological implications, but it remains controversial. Ten years ago we discovered a drainage system carved into the floor of the English Channel that is consistent with the catastrophic flood model. In this talk I will present a new compilation of geophysical data that we have used to analyse key landform features both within the downstream region and at the proposed breach point at the Straits of Dover. Our observations support the hypothesis that the landforms were initially carved by high-water volume flows via a unique catastrophic drainage of a pro-glacial lake in the southern North Sea at the Dover Strait rather than by fluvial erosion throughout the Pleistocene. The system also shows evidence for modification by a second flood that may have been a consequence of spillover of younger ice-marginal lake systems to the east, either in the North Sea basin or mainland Europe.

Water ice is a dominant material within the solar system, theorised to make up 50% of the mass of material beyond the solar system frost line. This leads to ice landscapes, features and bodies being studied using a number of techniques on number of differing planetary bodies. Recent explorations have shown more ice regions and landscapes on Pluto, Ceres and comet 67-P that have ignited many fields of planetary sciences to focus on the icy bodies from landscapes and internal structures to impact studies to cyrovolcanism to degassing of asteroids and comets and the implications for astrobiology.
The aim of this discussion meeting to discuss the latest research into the surface of icy bodies and regions in the solar system. We invite all whose work include the investigations of ices including weathering, astrobiology, landscapes and surfaces of different planetary bodies. We welcome research from all aspects of research including computational modelling, laboratory and field work.
Please send abstracts half page A4 (size 11 Arial) as PDF or word document to K.firstname.lastname@example.org by 5 pm Friday 29th October 2016.
