Gaia and the Unseen - The Brown Dwarf Question, a GREAT-ESF workshop

      We are pleased to announce the GREAT-ESF workshop

                    Gaia and the Unseen
                 The Brown Dwarf Question

          at Torino University on March 24-25-26 2014

  The ESA Gaia mission will revolutionise Astronomy.  It
  will impact almost all areas of study from minor planets,
  stars, and galaxies out to the distant QSO's.  The
  majority of brown dwarfs will be too faint for Gaia;
  however a subset of the closest, youngest, and most
  massive will be detectable along with a new population of
  companions detected via their gravitational effect on
  brighter primaries. When this conference takes place the
  Gaia mission will have started and we will have feedback
  on the efficiency and an update of its capabilities.  The
  meeting will concentrate on identifying what Gaia can do
  for brown dwarf science, what needs to be done outside of
  the mission, and a discussion of original ideas with a
  mixing of the brown dwarf and Gaia communities.

  The mornings will be dedicated to smaller parallel
  interactive sessions to foster an exchange of experience
  and a discussion of new ideas.*Suggested topics for**
**   these sessions are listed below but we encourage the**
**   community to indicate other ideas by October 15th via**
**   email togaiabds at  while the final program is**
**   still under development.*

  - Data-mining and the virtual observatory - Gaia CU9 tools,
    Topcat, CDS, astrogrid.
  - How Gaia will help us to determine binary parameters.
  - Using Gaia benchmark brown dwarfs to anchor and advance
    the next generation of atmosphere models.
  - Epsilon Ind BaBb a Gaia T dwarf: a case study.
  - The impact of Gaia on ground and space based brown dwarf
    astrometric programs.
  - Age determination for Brown Dwarfs
  - Brown Dwarf emissions from x-rays to radio.
  - Identifying and confirming moving groups members

  The afternoons will be standard conference presentations
  allocating time to submitted talks. Accepted talks will be
  biased to new and original proposals for the use of Gaia
  observations in studying brown dwarfs. Typically the 3
  days will be dedicated to, but not limited to, the
  following general themes:

  Day 1: Expectations of Gaia: Direct observations of
  ultra-cool and BDs; detection of BD companions. Hot BD

  Day 2: Synergies with Gaia: The impact of Gaia advances in
  stellar and galactic astrophysics on BD research; Gaia
  interactions with other surveys/instruments (e.g. Pan-STARRS,

  Day 3: Gaia and the exotic: Novel uses of Gaia observations
  for BDs; combining Gaia with JASMINE/WISE/Spitzer;
  micro-lensing possibilities; relativity and astrometry of

  Registration will be opened in early October. Updated

  We look forward to seeing you in Torino.
