About

David W. Coutts is a leading innovator in the field of ultra-compact, high-resolution astronomical spectrography, with a primary focus on exoplanet detection and asteroseismology. His most significant contribution is the design and development of the RHEA (Replicable High-resolution Exoplanet and Asteroseismology) spectrograph, a groundbreaking instrument that operates at the diffraction-limit by employing a single-mode fiber input. This revolutionary approach enables an exceptionally compact and stable design, making RHEA ideal for deployment on small, 0.2–0.4 m class robotic telescopes. Coutts’s work directly addresses the need for long-term, dedicated exoplanet monitoring programs by creating a spectrograph that is not only high-performing but also replicable, allowing for the creation of a cost-effective network of identical instruments. His foundational 2014 paper detailing RHEA’s opto-mechanical design has garnered 16 citations, while his 2016 follow-up on its performance and future developments has received 9 citations, underscoring his pivotal role in pushing the boundaries of precision radial velocity measurements with accessible, small-telescope platforms.
