We present new statistical parallax solutions for the absolute magnitude and kinematics of RR Lyrae stars. We have combined new proper motions from the Lick Northern Proper Motion program with new radial velocity and abundance measures to produce a data set that is 50% larger, and of higher quality, than the data sets employed by previous analyses. Based on an a priori kinematic study, we separated the stars into halo and thick disk sub-populations. We performed statistical parallax solutions… Expand
The absolute magnitude of RRC variables from statistical parallax
We present the first definitive measurement of the absolute magnitude of RR Lyrae c-type variable stars (RRc) determined purely from statistical parallax. We use a sample of 242 RRc variablesExpand
The RR Lyrae Distance Scale
We review seven methods of measuring the absolute magnitude Mv of RR Lyrae stars in light of the Hippareos mission and other recent developments. We focus on identifying possible systematic errorsExpand
A New Analysis of RR Lyrae Kinematics in the Solar Neighborhood
Full space velocities are computed for a sample of 130 nearby RR Lyrae variables using both ground-based and Hipparcos proper motions. In many cases proper motions for the same star from multipleExpand
The Absolute Magnitude of RR Lyrae Stars Derived from the Hipparcos Catalogue
The present determination of the absolute magnitude MV(RR) of RR Lyrae stars is twofold, relying upon Hipparcos proper motions and trigonometric parallaxes separately. First, applying the statisticalExpand
Systematics of RR Lyrae Statistical Parallax. II. Proper Motions and Radial Velocities
We investigate whether a misestimate of proper motions or radial velocities could have been a source of substantial systematic errors in the statistical parallax determination of the absoluteExpand
Kinematics and multiband period–luminosity–metallicity relation of RR Lyrae stars via statistical parallax
This paper presents results from photometric and statistical-parallax analysis of a sample of 850 field RR Lyrae (RRL) variables. The photometric and spectroscopic data for sample RRLs are obtainedExpand
Subsystems of RR Lyrae variable stars in our Galaxy
We have used published, high-accuracy, ground-based and satellite proper-motion measurements, a compilation of radial velocities, and photometric distances to compute the spatial velocities andExpand
Statistical Parallax Analysis of SDSS M Dwarfs
We report on the analysis of ~22,000 M dwarfs using a statistical parallax method. This technique employs a maximum-likelihood formulation to simultaneously solve for the absolute magnitude, velocityExpand
RR Lyrae Variables in the Inner Halo. I. Photometry
I present V-band CCD photometry for a sample of 103 RR Lyrae variables selected from the General Catalogue of Variable Stars to lie in the inner halo of the Galaxy (3 kpc < RGC < 6 kpc). I alsoExpand
Analysis of RR Lyrae Stars in the Northern Sky Variability Survey
We use data from the Northern Sky Variability Survey (NSVS), obtained from the first-generation Robotic Optical Transient Search Experiment (ROTSE-I), to identify and study RR Lyrae variable stars inExpand
