A Hubble Space Telescope transit light curve for GJ436b
J. L. Bean, G. F. Benedict, D. Charbonneau +6
We present time series photometry for six partial transits of GJ436b obtained with the Fine Guidance Sensor instrument on the Hubble Space Telescope (HST). Our analysis of these da…
HST FGS astrometry - the value of fractional millisecond of arc precision
G. Fritz Benedict, Barbara E. McArthur, Jacob L. Bean
In a few years astrometry with the venerable combination of Hubble Space Telescope and Fine Guidance Sensor will be replaced by SIM, GAIA, and long-baseline interferometry. Until t…
A new calibration of Galactic Cepheid Period-Luminosity relations from B to K bands, and a comparison to LMC PL relations
P. Fouque, P. Arriagada, J. Storm +8
The universality of the Cepheid Period-Luminosity relations has been under discussion since metallicity effects have been assumed to play a role in the value of the intercept and,…
Detection of a Third Planet in the HD 74156 System Using the Hobby-Eberly Telescope
Jacob L. Bean, Barbara E. McArthur, G. Fritz Benedict +1
We report the discovery of a third planetary mass companion to the G0 star HD 74156. High precision radial velocity measurements made with the Hobby-Eberly Telescope aided the dete…
HST/FGS Parallaxes of AM CVn Stars and Astrophysical Consequences
G. H. A. Roelofs, P. J. Groot, G. F. Benedict +5
We present absolute parallaxes and relative proper motions for five AM CVn stars, which we obtained using the Fine Guidance Sensors on board the Hubble Space Telescope. Our paralla…
The Mass of the Candidate Exoplanet Companion to HD 33636 from Hubble Space Telescope Astrometry and High-Precision Radial Velocities
Jacob L. Bean, Barbara E. McArthur, G. Fritz Benedict +4
We have determined a dynamical mass for the companion to HD 33636 which indicates it is a low-mass star instead of an exoplanet. Our result is based on an analysis of Hubble Space…
