As one of the 12 legacy programmes given ~300 hrs observing time on the newly enhanced e-MERLIN; the Cygnus OB2 Radio Survey (COBRaS) (homepage: http://www.homepages.ucl.ac.uk/~ucapdwi/cobras/) is an intensive deep-field mapping of the Cyg OB2 association in the Cygnus region of our Galaxy. This will provide the most detailed census for the most massive OB association in the northern hemisphere. A range of astrophysical problems and themes will be investigated including: mass loss and evolution of massive stars; the formation, dynamics and content of massive OB associations and the frequency of massive binaries and the incidence of non-thermal radiation.
As part of of the initial ground work for this project, extensive meta-data catalogues were amalgamated from various catalogues from the Virtual Observatory database. In this talk I will discuss; investigations into JHK photometric techniques which can help identify possible OB candidates and other spectral classes; theoretical mass loss models as described by Vink et al. 2001 along with stellar parameters from Martins et al. 2005, Searle et al. 2008 and Prinja et al 1990 which pave the way to calculate theoretical mass loss rates for smooth winds of O stars and B supergiants, and the predicted 6cm fluxes resulting from the thermal free-free radiation in their winds. This will be essential for the study of clumped winds which is an early goal for this project.
Over the months following from when this abstract was written; the first e-MERLIN pointings are expected. In the event of obtaining data, this will also be included in the presentation as part of the 'early science' from e-MERLIN and COBRaS.
