- Abstract
As part of the VISTA Science Verification programme, a large set ofimages in Orion was obtained at five near-infrared wavelength bands,from 0.9 to 2.2 μm. The resulting multi-band catalogue contains approximately three million sources, allowing investigation of various issues concerning star and brown dwarf formation, such as a) the difference in the shape of the substellar mass function in a cluster vs.non-clustered environment, b) the influence of massive OB stars on the process of brown dwarf formation, c) the size and morphology of dust envelopes around protostars, and d) the comparative role of mass and environment on the evolution of circumstellar discs. The data from the VISTA Orion Survey, including catalogues, are available to the community. In this article we present an overview of selected sciencer esults that have emerged so far from this survey.
