Massive Stars and the Gaia-ESO Survey
Brussels, Belgium, 5-7 May 2015
Despite their importance for the star-formation history of the Universe, massive stars are
particularly poorly understood. However, thanks to projects such as the ongoing
Gaia-ESO Survey (GES)
and the VLT-Flames Tarantula Survey (VFTS) progress in the number of massive stars with accurate
parameters is rapidly growing.
In order to bring together the European expertise in massive-star spectral analysis and evolution
it is timely to organise a Workshop on massive stars in the context of the
By the time of the meeting about two-thirds of the GES data will have been collected. The data reduction and analysis
techniques will have been refined to handle these data and produce significant science output.
One aim of the workshop is to present the GES results to a wider community of massive-star experts. The interaction between the
various European massive-star groups will allow us to extract the best science from the GES data. A second purpose is to
interact with the other GES Co-Is to provide them with the information they need related to e.g. cluster studies. Finally,
it is a timely moment to measure the progress we have made in achieving the science cases listed in the GES proposal and to
address future directions.
