Results for "Hubble Space Telescope Astrometry Team"

This group uses the Fine Guidance Sensors aboard Hubble Space Telescope to measure star positions and study binary stars unresolvable using ground-based techniques. The Fine Guidance Sensors provide per-observation relative positions with 0.001 arc second angular precsion. Stellar positions yield information on distance (parallax) and possible faint companions. The orbits of binary stars yield stellar masses.
