Understanding substellar populations and atmospheres: from brown dwarfs to exo-planets

Principal contact: B. Burningham (b.burningham@herts.ac.uk)

Organisers: B. Burningham (Hertfordshire, UK), J. Farhi (Leicester, UK), M. Gillon (Geneva, Switzerland), D. Homeier (Goettingen, Germany), N. Lodieu (IAC, Spain), J. Patience (Exeter, UK), D. Pinfield (Hertfordshire, UK), D. Pollacco (QUB, UK), I. Snellen (Leiden, The Netherlands)

The study of exo-planets has progressed to the point that direct detection of these objects via imaging has become a reality. Recent results have provided exciting images of very low mass companions, and ongoing and future surveys will further explore the population of planets in wide orbits and the properties of their atmospheres. However, transiting planetary systems are currently the most important source of information about the physics and composition of exo-planetary objects. Instrumentation under construction for 8m telescopes and planned future facilities such as the E-ELT and JWST will greatly extend the capabilities of direct imaging planet searches, and studies of transiting planets.

The discovery of free-floating sub-stellar objects with effective temperatures as low as 500K, and future discoveries of objects cool enough to harbour water clouds, provide an alternative window on the physics of cool sub-stellar atmospheres. Without the glare of a nearby bright primary star, these objects provide ideal laboratories for improving the atmospheric models required to effectively interpret observations of cool giant exo-planets.

In this series of five sessions we aim to bring together recent cutting edge observations and models of substellar atmospheres from both the brown dwarf and exo-planet communities, and discuss capabilities anticipated with future instruments.
