2021 Tinsley Prize
Bill Paxton was awarded the 2021 Beatrice M. Tinsley Prize “for his inspired work on providing, maintaining, and supporting the use of open-source stellar-evolution codes that have seeped into the foundation of research and education efforts and have given rise to an immense amount of new research across multiple subfields of astrophysics.” The Tinsley Prize, awarded every two years by the American Astronomical Society, recognizes an outstanding research contribution to astronomy or astrophysics of an exceptionally creative or innovative character.
