Austin F. Gulliver

Dr. Austin F. Gulliver is a Professor and Chair of the Department of Physics & Astronomy at Brandon University. His research focuses on the analysis of stellar spectra and atmospheres, particularly for hot stars, using high signal-to-noise (S/N) data from the Dominion Astrophysical Observatory (DAO) and other facilities. He leads the Astrophysical GF Values Project, which aims to refine atomic line parameters (e.g., oscillator strengths) for astrophysical applications.

His collaborations include Dr. Graham Hill (University of Auckland) and Dr. Saul Adelman (The Citadel), with work centered on developing software tools like CCDSPEC (spectroscopic reduction) and STELLAR (stellar parameter fitting). Key projects involve spectral atlases of stars like Vega, Deneb, and o Pegasi, emphasizing high-resolution data and their role in galactic chemical evolution studies.

Research interests span stellar hydrodynamics, convection modeling (e.g., Canuto-Mazzitelli theory), and instrument design, including the ASTRA Spectrophotometer. His work addresses systematic errors in abundance analyses and bridges observational astronomy with atomic physics.

Publications emphasize high-precision spectral analysis, elemental abundances in A/F-type stars, and the development of spectroscopic tools. His team’s spectral atlases provide critical data for studies of stellar composition and astrophysical processes.
