Astrometric detection of rocky exoplanets from inexpensive space platforms

The detection of orbiting exoplanets by way of astrometric monitoring of the host star to reveal gravitationally induced reflex motion requires extreme precision and measurement stability when targeting Earth-mass objects. Despite this, astrometry is widely regarded as the most promising avenue for the most desired of...

ADORA: a differentiable optical modeling and astrometric retrieval framework for SHERA

ADORA provides a flexible framework for studying astrometric extraction, calibration-bias diagnosis, and future SHERA requirements, and Pixel-position errors across the tested range remain near the matched-model recovery scale indicating robustness to certain detector calibration errors.
