About
Anthony Cassette is a leading figure in the field of precision radial velocity instrumentation, specializing in the development of high-resolution optical spectrographs for exoplanet detection. His most impactful work centers on the design, characterization, and on-sky deployment of the TOU spectrograph—a compact, very high-resolution instrument (R=100,000) operating in the 0.38–0.9 micron range. Cassette’s key contribution was demonstrating the TOU spectrograph’s Doppler performance at the 2-meter Automatic Spectroscopy Telescope (AST) at Fairborn Observatory, where his pilot survey of 12 bright FGK dwarfs in 2015 achieved the precision necessary to detect low-mass planets. This work, cited 3 times, established a new benchmark for compact, robotic spectrographs, proving that high-resolution, cost-effective instruments could rival larger facilities in radial velocity stability. Cassette’s achievements underscore his role in advancing the accessibility of exoplanet detection technology, making him a notable innovator in the field. His research continues to influence the design of next-generation spectrographs for ground-based surveys.
