About

Dr. Simon Gross is a leading figure in astronomical instrumentation, with his research centered on the development of high-resolution spectrographs for exoplanet detection and asteroseismology. His most notable contribution is the design and realization of the Replicable High-resolution Exoplanet and Asteroseismology (RHEA) spectrograph, a groundbreaking instrument that operates at the diffraction limit by employing a single-mode fiber input. This innovation allows RHEA to be remarkably compact while maintaining exceptional precision, making it ideal for deployment across a network of small robotic telescopes. Dr. Gross’s work on the RHEA spectrograph, detailed in his highly cited 2016 paper, has laid the foundation for a new class of scalable, cost-effective instruments that can be replicated to dramatically increase observational coverage. By enabling high-resolution spectroscopy on modest telescopes, his contributions are pivotal in democratizing access to cutting-edge exoplanet science and stellar astrophysics, with the potential to accelerate discoveries of Earth-like worlds and stellar oscillations.
