Science with the One Metre Initiative

Science with the One Metre Initiative is driven by its performance, capabilities and site. Primary among these is the OMI's ultra-wide field of almost 5 degrees². Coupled with a high performance camera, fully corrected focal plane, prime focus optical configuration, active optics, low mass primary mirror, carbon fibre sandwich core and fully autonomous nature make, for an overall high performance and high throughput telescope.

The OMI science potential is multifaceted, its core scientific long term project is to detect planets around red-dwarf stars. Its wide field nature makes it ideal for a host of other research projects, such as near Earth Object Detection (NEO), supernovae search, galactic structure, galaxy clusters and super-clusters, astrometry, a wide-field photometry among others.

KEY SCIENCE AREAS

• Galactic structure
• Galaxy clusters and super-clusters
• Near Earth Object Search
• Earth-like planet search around red dwarf stars
• Astrometry
• Wide-Field photometry
• Supernovae search
• Variable star study in the local group
• Galactic light-echo search

The Canadian astronomical community, who lack a wide field imaging telescope will now have a powerful tool that will open up a host possible research possibilities.

The key features of the OMI are its ability to map large areas of the sky with good sensitivity and provide significant one-site computing power to permit real time image analysis and data extraction. The science projects described here utilize one or both of these abilities.
