Micro-arcsecond Astrometry Technology: Detector and Field Distortion Calibration [IMA]

http://arxiv.org/abs/2212.08129


Microarcsecond (uas) astrometry provides an indispensable way to survey earth-like exoplanets and fully characterize the orbits and masses for assessing their habitability. Highly accurate astrometric measurements can also probe the nature of dark matter, the primordial universe, black holes, and neutron stars for new astrophysics. This paper presents technology for calibrating array detectors and field distortions to achieve narrow field uas astrometry using a 6 m telescope with a focal plane array detector.
