Dr. Peter Stetson of the National Research Council Herzberg Astronomy and Astrophysics has been given the 2016 Dunlap Award at the annual meeting of the Canadian Astronomical Society in Winnipeg.

Dr. Stetson obtained his Ph.D. in astronomy at Yale in 1979. After a short research fellowship at Yale he took a Carnegie Fellowship at the Mount Wilson and Las Campanas Observatories, subsequently moving to the Dominion Astrophysical Observatory (DAO) of NRC-Herzberg in 1983.Dr. Stetson has been the principal research officer at DAO since 2003. He was elected as a Fellow of the Royal Society of Canada in 2006 and was awarded the George van Biesbroeck Prize of the American Astronomical Society in 2008.

To address the problem of measuring the properties of stars in digital images from the earliest CCDs, Dr. Stetson developed and released the DAOPHOT program in 1986. He has single-handedly maintained, improved, and supported it since then. Countless investigators have used DAOPHOT; the Hubble Space Telescope Key Project to measure the distance scale of the universe and the Nobel Prize-winning discovery of dark energy are but two transformational scientific results that exploit its photometry.

Dr. Stetson’s more recent spectral line measurement code, DAOSPEC, has been adopted by many of the world’s largest optical facilities. Additionally, Dr. Stetson’s carefully calibrated, freely available photometric standard star catalog now exceeds 114,000 objects and underpins the majority of photometric observations carried out today. Dr. Stetson has also long served as an image structure expert for senior National Research Council engineers, impacting the design of instruments for the next generation of large facilities such as the Thirty Meter Telescope.
