Astrometry with Hubble Space Telescope Fine Guidance Sensors - A Review
G. Fritz Benedict, Barbara E. McArthur, Edmund P. Nelan +1
Over the last 20 years Hubble Space Telescope Fine Guidance Sensor interferometric astrometry has produced precise and accurate parallaxes of astrophysical interesting stars and ma…
Astrometry with the Hubble Space Telescope: Trigonometric Parallaxes of Selected Hyads
Barbara E. McArthur, G. Fritz Benedict, Thomas E. Harrison +1
We present absolute parallaxes and proper motions for seven members of the Hyades open cluster, pre-selected to lie in the core of the cluster. Our data come from archival astromet…
Metallicities of M Dwarf Planet Hosts from Spectral Synthesis
Jacob L. Bean, G. Fritz Benedict, Michael Endl
We present the first spectroscopic metallicities of three M dwarfs with known or candidate planetary mass companions. We have analyzed high resolution, high signal-to-noise spectra…
The Extrasolar Planet epsilon Eridani b - Orbit and Mass
G. Fritz Benedict, Barbara E. McArthur, George Gatewood +11
Hubble Space Telescope observations of the nearby (3.22 pc), K2 V star epsilon Eridani have been combined with ground-based astrometric and radial velocity data to determine the ma…
Detection of a NEPTUNE-mass planet in the Cancri system using the Hobby-Eberly Telescope
Barbara E. McArthur, Michael Endl, William D. Cochran +9
We report the detection of the lowest mass extra-solar planet yet found around a Sun-like star - a planet with an \msini of only 14.21 2.91 Earth masses in an extremely short…
The Solar Neighborhood IX: Hubble Space Telescope Detections of Companions to Five M and L Dwarfs within 10 pc of the Sun
D. A. Golimowski, T. J. Henry, J. E. Krist +10
We report the detections of low-mass companions to five M and L dwarfs within 10 pc of the Sun using the Hubble Space Telescope (HST) Near-Infrared Camera and Multi-Object Spectrom…
