Astrometry.jl: A Fundamental Julia Package for Astronomy by Paul Barrett PreTalx: https://pretalx.com/juliacon-2025/tal... Astrometry is the science of positional astronomy. It involves the measurements of the locations, velocities, and distances of celestial objects, such as stars, planets (including Earth), and space probes. The Astrometry package implements basic astrometric algorithms that are fast and simple to use. For example, it enables users to perform barycentric corrections for the time, position and velocity of celestial objects. It reduces the number of functions in the International Astronomical Union's (IAU) Standards of Fundamental Astronomy (SOFA) library from 533 to no more than a few dozen. It also contains a sub-package that implements the complete set of SOFA functions in Julia. It is therefore a drop-in replacement for the Julia wrapped FORTRAN and C SOFA libraries.
