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.
A RAS Specialist Discussion Meeting organised by *Licia Ray (Lancaster); Jonathan Nichols (Leicester); Sarah Badman (Lancaster)
Energy and momentum are transferred between a planetary atmosphere and its surrounding plasma environment through the high-latitude magnetosphere. In this region, which is characterised by a strong magnetic field and low plasma density, magnetospheric particles are accelerated as they descend down towards the planetary atmosphere, where they can generate intense auroral emissions. Single spacecraft (e.g. FAST) and constellation missions (e.g. Cluster) have extensively explored Earth's high-latitude magnetosphere over the past two decades. The host of ground- and space-based support, along with in situ measurements, numerical models, and theoretical descriptions have helped to build a global picture of the underlying drivers and physical processes that contribute to spatial and temporal variations in these high-latitude regions, although outstanding questions such as the nature of the particle acceleration remain.
In contrast, Juno and Cassini Grand Finale missions are currently investigating the high-latitude magnetospheric regions of Jupiter and Saturn, respectively, with unprecedented detail, providing ground-breaking in-situ data. Both missions are complemented by Earth-based remote observations, numerical and theoretical models.
This specialist discussion meeting will compare in situ measurements, remote observations, theoretical descriptions, and numerical models of the high-latitude regions of Earth, Jupiter, and Saturn, offering insight into how differing magnetospheric properties i.e. magnetic field strength, plasma sources, rotation rates, solar-wind interaction, influence the properties of the high-latitude magnetosphere and affect the universal processes of auroral acceleration, magnetosphere-ionosphere coupling. Participation is encouraged from the terrestrial and planetary communities with an eye towards increased collaboration.

A RAS Specialist Discussion Meeting organised by Dr Mike Childress (Southampton);
We are entering a golden-age in the study of optical transients. Many surveys with leading UK involvement are reaching maturity in both the imaging and spectroscopic domains. These have provided rich datasets for cosmological studies (e.g., with type Ia supernovae), and diverse datasets with which to explore the extragalactic transient universe, revealing unexpected types of cosmic explosions and transient events (e.g., superluminous supernovae, tidal disruption events). Progress in the next few years may see the first optical/IR counterparts of both gravitational wave sources and fast radio bursts. Simultaneously, these data are inspiring new state-of-the art theoretical models to uncover the detailed physics. With new time-domain surveys and instruments/facilities on the horizon such as the Large Synoptic Survey Telescope (LSST) and the Zwicky Transient Factory (ZTF), this meeting will review the current status of optical transient science and look to the future of what may be revealed by the next generation of cutting-edge facilities. We welcome contributions on all aspects of extragalactic optical transients, observational and theoretical, both science-focussed and forward-looking to new facilities.

2017 EDDINGTON LECTURE
Our Galaxy is thought to be dynamically young with a fairly smooth potential dominated by a nearly spherical dark matter halo that has evolved little in the last several billion years. These attributes broadly suggest that potential evolution and dynamical chaos should have negligible influences on the orbits of its constituent stars, as well as on the stellar structures they collectively support. This talk reviews some recent results which point to signatures of Galactic evolution and the chaotic nature of stellar orbits that can be (and have been) observed.

The Study of the Earth's Deep Interior (SEDI) focusses on the study of Earth's mantle and core and has links to comparative planetology. The meeting will comprise invited review talks, contributed student-presented talks and include discussion about the big, unsolved questions in deep Earth research. Additionally we will have the opportunity for poster presentations over an extended lunch. This meeting will help to identify important topics in deep Earth research to which the UK SEDI community might contribute and we hope to foster new collaborations between UK and international deep Earth researchers. Submissions for contributed talks (abstract required) or posters (title required) on any SEDI-related theme are welcome.
For more details and abstract submission, see the meeting website at:
The AGM is only open to Fellows; non-Fellows intending to attend the following Ordinary meeting are welcome to wait in the Lower Library of the Geological Society.
