Title: The SCORPIO project: Stellar radio emission in the SKA era

Abstract: Radio emission has been detected in a broad variety of stellar objects from all stages of stellar evolution. However, most of our knowledge originates from targeted observations of small samples, which are strongly biased to source which are peculiar at other wavelengths. In the absence of unbiased searches, it is very difficult to predict what will be found by SKA and its pathfinders such as ASKAP-EMU.

The SCORPIO project is a ATCA deep survey at 1.4 GHz in the Galactic plane with goal to reach a flux limit of 40/uJy. The main scientific output will be the production of catalogues of different populations of Galactic radio sources, from stars to star forming regions and Supernovae Remnants. Moreover, the SCORPIO project will guide EMU design in identifying issues arising from the complex continuum structure associated with the Galactic Plane and from the variable sources in the Galactic Plane. It will contribute in evaluating the most appropriate method for source finding and extraction for sources embedded in the diffuse emission expected at low Galactic latitude.
