FEEDBACK FROM BREAKOUT SESSION C:

GENERAL COMMENTS: The purpose of this session is to bring together different groups dealing with heterogeneous topics like:

- Exoplanets

- Relativity & Fundamental Physics

- Reference Frame

- Solar System

- Non-Single Stars

The overall discussion allowed to identify converging interests in GREAT to improve Gaia science returns. For example:

- Support cooperation between European institutes

- Organisation of Conference/Workshops/Training

- Help carry out follow-up or complementary observations.

For a general summary of the discussion see the attached presentation by F. Mignard. Individual contributions to the discussion are listed below:

CONTRIBUTIONS:

..Alessandro Sozzetti, INAF-OATo: summary of exoplanets EoI (see attached file, and institute presentation)

..Simon Hodgkin, IoA, Cambridge: the Gaia case for transiting planets

..Mariateresa Crosta, INAF-OATo: brief recap of OATo requests/interests for GR and FP activities (see attached EoI, and institute presentation).

..Daniel Hestroffer, IMCCE, Paris: Paris activity summary on solar system objects (see attached EoI)

..Tadeusz Michalowski, Astronomical Obs., Poznan: asteroid lightcurves from Gaia and ground-based observations

..Josef Durech, Charles Univ, Prague: topics of interest related to Gaia photometry and astrometry of asteroids (see institute presentation)

..Francois Mignard, OCA, Nice: how to link optical and radio RF, needs for asteroid follow-up observations

..Tom Marsh, Warwick: discussion on interests related to Gaia & white dwarf binaries (see institute presentation)

Original Themes for activities from the EoIs and new themes of interest identified during the discussion in BS C are listed below (proposers nationality in brackets):

EXOPLANETS

..Training school on novel methods of micro-arcsec astrometry (in combination with GR/FP) (I)

..large workshop on Exoplanets and solar system in the Gaia era (I)

..Exchange visits between institutes in Italy, France, Poland, Belgium, England, Switzerland, USA

..Public outreach activities (I)

RELATIVITY/FUNDAMENTAL PHYSICS

..Training school on novel methods of micro-arcsec astrometry (in combination with exoplanets) (I)

..workshop on The link between relativistic astrometry and cosmology (I)

..Exchange visits between institutes in Italy, France, Germany, Brazil (I)

..Public outreach activities, particularly multi-media tools, booklets etc. (I)

REFERENCE FRAME

..Exchange visits and possible workshops devoted to the future construction of celestial frames before and after Gaia (see attached EoI) (F)

SOLAR SYSTEM

..training school on the exploitation of asteroid light-curves (inversion problems) (CZ)

..training school on dynamical modelling with non-gravitational forces: surface and shape properties, light scattering, Yarkovsky effect, thermal modelling (PL,CZ)

..Exchange visits between Italy, France, Germany, Poland, Czech Republic, Finland

NON-SINGLE STARS

..training school in the physics of WD and the binary populations (UK)

..workshop on binarity in the solar system (already planned in Poznan) (PL)

..workshop on binarity in white dwarfs and preparation of follow-up observations (UK)

..workshop on active and interacting binaries (I)

Themes of interest identified by breakout session C are listed below (proposers nationality in brackets).

General need for follow-up / support observations:

..Follow-up observations for Solar System alerts, in cooperation with non EU eastern countries (F)

..Systematic occultation program with prediction based on the Gaia intermediate release ? shape and size of asteroids (F)

..Astrometric observations before and after Gaia mission of a sample of asteroids to improve the Gaia masse determination (F)

..Spectroscopic observations (radial velocities with precision ~ 1-10 m/s) for Gaia targets with sub-stellar mass companions (I)

..Support VLBI observations to get maps of the ICRF sources to be used for the frame alignment. (F)

Interdisciplinary interests/activities in BS C are listed below (proposers nationality in brackets):

1) Connections between planetary systems formation and very low-mass star formation (I)

2) Connections between GR, fundamental physics, and cosmology, in particular:

..General relativistic modeling of the Galaxy rotation curve and implications for its dark matter content (I)

..Galaxy velocity dispersions in General Relativity (I)

..Workshop/symposium/training school on the general relativistic modeling of the Galaxy. (I)

3) Conference on “The fundamental cosmic distance scale”, to coincide with OATo’s 250th birthday,Torino selected by ESOF as European City of Science 2010 (I)
