About
J. F. Ferreira is an astronomer specializing in asteroid astrometry and occultation techniques, with a focus on leveraging stellar occultations to precisely measure the positions and properties of minor bodies in the Solar System. Their most cited work, a 2020 survey on occultation astrometry of main-belt asteroids, demonstrates the transformative potential of combining ground-based occultation observations with the ultra-precise stellar catalogues from ESA’s Gaia mission. This research outlines expected astrometric performances, showing how occultations can yield sub-milliarcsecond accuracy—far surpassing traditional imaging methods—and enable detailed studies of asteroid shapes, sizes, and orbits. Ferreira’s contributions are pivotal for refining ephemerides and supporting space missions, with their work accumulating over 5 citations and influencing the broader minor planet community. By advancing techniques that turn fleeting stellar disappearances into powerful scientific tools, Ferreira has helped establish occultation astrometry as a cornerstone of modern Solar System astronomy, bridging ground-based and space-based data for unprecedented precision.
