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. 




Accretion States and Feedback
Date: 10 Apr 2015
Time: 10:30

An RAS Specialist Discussion Meeting organised by Rob Fender (Oxford)*, Steve Balbus (Oxford), Chris Done (Durham), Christian Knigge (Southampton)

*Contact: rob.fender AT astro.ox.ac.uk

 

Distinct accretion "states", distinguished by their spectral and temporal properties, which in turn reflect the geometry, optical depth and radiative efficiency of the accretion flows, have been clearly identified in white dwarfs, stellar-mass black holes and neutron stars. These states have been clearly linked to modes of kinetic and radiative feedback in complex but repeatable ways. They have also probably been

identified in supermassive black holes, and understanding the duration and luminosity of a state in any given time period may be the key to understanding feedback from AGN over cosmological time. In this meeting we will summarize and discuss the state of the art in our empirical understanding of these accretion states and associated feedback, and some of the underlying theories for their origin.

Spectroscopy of Airless Bodies in wavelengths from the visible to the microwave: Orbital, Telescopic and/or Laboratory Measurements relevant to Mercury, the Moon and Asteroids
Date: 10 Apr 2015
Time: 10:30

An RAS Specialist Discussion Meeting organised by Kerri Donaldson Hanna* and Neil Bowles (Oxford), Stephen Lowry (Kent), and Simon Green (Open University)

*Contact: DonaldsonHanna AT atm.ox.ac.uk

 

Airless planetary bodies like Mercury, the Moon and asteroids provide a unique opportunity for studying the formation and evolution of planetary surfaces, as there is no weather or liquid water altering their surfaces. Using the individual strengths of each spectroscopic technique, the composition of a planet's surface can be determined through the identification of spectrally dominant minerals exposed at the surface. Our current knowledge of surface compositions come from the analyses of 1) remotely sensed data from spacecraft and telescopes and 2) laboratory measurements of returned sample material or analogues. Join us for a day of discussion on all things spectroscopic of the airless bodies!
