Artist's impression of one of the planets circling Epsion eridani (from Nova Celestia ) | The overwhelming majority of extrasolar planetary systems have been identified through radial velocity monitoring, and the detection of the reflex motion of the parent star as it orbits the common center of mass of the system. Just as radial velocities measure the stellar "wobble" introduced along the line of sight, so high precision astrometry can be used to measure motion in the plane of the sky. Combining these data gives the full three-dimensional motions of the system, and a direct measure of the mass of the planetary companion. The Fine Guidance Sensors on HST are the only system currently capable of making observations at the required sub-milliarcscond accuracy, and has already been used for astrometry of several systems, including the M dwarf Gl 876 and, most recently, Epsilon Eridani. The current GO program pursues observations of six planetary hosts, and FGS observations of HD 38529, which has at least two planetary companions, are scheduled over the next week. |
