NASA has awarded Justin R. Crepp, the Freimann Assistant Professor of Physics at the University of Notre Dame, with an Early Career Fellowship. He is the only awardee in the nation to receive the fellowship in the Origins of Solar Systems program. Crepp’s project, “Working at the Diffraction Limit: New Exoplanetary Science in the Era of ‘Extreme’ Adaptive Optics,” was selected through a competitive proposal process, followed by peer review in a second round of evaluation.
With funding from NASA, Crepp will build the world’s first diffraction-limited Doppler spectrometer. The instrument concept, named “iLocater”, will record ultra-precise radial velocity measurements of nearby stars at infrared wavelengths, and discover Earth-like planets orbiting the smallest and most common stars in the galaxy — the so-called “M-dwarfs.” It will also characterize their orbits and potentially the planets’ atmospheres to search for signs of life.
