Spectral Properties of Cool Stars: Extended Abundance Analysis of 1,617 Planet-search Stars
Valenti, Jeff A.; Fischer, Debra A.; Brewer, John M. +1 more
We present a catalog of uniformly determined stellar properties and abundances for 1,617 F, G, and K stars using an automated spectral synthesis modeling procedure. All stars were observed using the HIRES spectrograph at Keck Observatory. Our procedure used a single line list to fit model spectra to observations of all stars to determine effective…
A Comprehensive Census of Nearby Infrared Excess Stars
Song, Inseok; Cotten, Tara H.
The conclusion of the Wide-Field Infrared Survey Explorer (WISE) mission presents an opportune time to summarize the history of using excess emission in the infrared as a tracer of circumstellar material and exploit all available data for future missions such as the James Webb Space Telescope. We have compiled a catalog of infrared excess stars fr…
Spectroscopic Survey of G and K Dwarfs in the Hipparcos Catalog. I. Comparison between the Hipparcos and Photometric Parallaxes
Lee, Young Sun; Stauffer, John R.; Terndrup, Donald M. +3 more
The tension between the Hipparcos parallax of the Pleiades and other independent distance estimates continues even after the new reduction of the Hipparcos astrometric data and the development of a new geometric distance measurement for the cluster. A short Pleiades distance from the Hipparcos parallax predicts a number of stars in the solar neigh…
