Astrometry with Hubble Space Telescope Fine Guidance Sensors—A Review
Nelan, Edmund P.; Harrison, Thomas E.; Benedict, G. Fritz +1 more
Over the last 20 years, Hubble Space Telescope Fine Guidance Sensor interferometric astrometry has produced precise and accurate parallaxes of astrophysical interesting stars and mass estimates for stellar companions. We review parallax results, and binary star and exoplanet mass determinations, and compare a subset of these parallaxes with prelim…
A New Method for Wide-field Near-IR Imaging with the Hubble Space Telescope
van Dokkum, Pieter G.; Franx, Marijn; Muzzin, Adam +6 more
We present a new technique for wide and shallow observations using the near-infrared channel of Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST). Wide-field near-IR surveys with HST are generally inefficient, as guide star acquisitions make it impractical to observe more than one pointing per orbit. This limitation can be circumvente…
