The Bulge Radial Velocity Assay (BRAVA): II. Complete Sample and Data Release
Andrea Kunder, Andreas Koch, R. Michael Rich +13
We present new radial velocity measurements from the Bulge Radial Velocity Assay (BRAVA), a large scale spectroscopic survey of M-type giants in the Galactic bulge/bar region. The…
Know the Star, Know the Planet. II. Speckle Interferometry of Exoplanet Host Stars
Brian D. Mason, William I. Hartkopf, Deepak Raghavan +4
A study of the host stars to exoplanets is important to understanding their environment. To that end, we report new speckle observations of a sample of exoplanet host primaries. Th…
Non-Blazhko RR Lyrae Stars Observed with the KEPLER Space Telescope
J. M. Nemec, R. Smolec, J. M. Benko +22
This paper summarizes the main results of our recent study of the non-Blazhko RR Lyrae stars observed with the Kepler space telescope. These stars offer the opportunity for studyin…
The Solar Neighborhood. XXVI. AP Col: The Closest (8.4 pc) Pre-Main-Sequence Star
Adric R. Riedel, Simon J. Murphy, Todd J. Henry +3
We present the results of a multi-technique investigation of the M4.5Ve flare star AP Col, which we discover to be the nearest pre-main-sequence star. These include astrometric dat…
The Solar Neighborhood XXVII: Discovery of New Proper Motion Stars with mu > 0.18 "/yr in the Southern Sky with 16.5 > R_59F > 18.0
Mark R. Boyd, Todd J. Henry, Wei-Chun Jao +2
Here we present 1584 new southern proper motion systems with mu > 0.18 "/yr and 16.5 > R_59F > 18.0. This search complements the six previous SuperCOSMOS-RECONS (SCR) proper motion…
Fourier analysis of non-Blazhko ab-type RR Lyrae stars observed with the Kepler space telescope
J. M. Nemec, R. Smolec, J. M. Benko +22
Nineteen of the ~40 RR Lyr stars in the Kepler field have been identified as candidate non-Blazhko (or unmodulated) stars. In this paper we present the results of Fourier decomposi…
