The Luminosity and Mass Functions of Low-Mass Stars in the Galactic Disk: I. The Calibration Region
Kevin R. Covey, Suzanne L. Hawley, John J. Bochanski +6
We present measurements of the luminosity and mass functions of low-mass stars constructed from a catalog of matched Sloan Digital Sky Survey (SDSS) and 2 Micron All Sky Survey (2M…
Cool Subdwarf Investigations (CSI) I: New Thoughts for the Spectral Types of K and M Subdwarfs
Wei-Chun Jao, Todd J. Henry, Thomas D. Beaulieu +1
Using new spectra of 88 K and M-type subdwarfs, we consider novel methods for assigning their spectral types and take steps toward developing a comprehensive spectral sequence for…
The Solar Neighborhood. XX. Discovery and Characterization of 21 New Nearby White Dwarf Systems
John P. Subasavage, Todd J. Henry, P. Bergeron +2
We present medium resolution spectroscopy and multi-epoch VRI photometry for 21 new nearby (< 50 pc) white dwarf systems brighter than V ~ 17. Of the new systems, ten are DA (inclu…
Angular Diameters of the G Subdwarf Cassiopeiae A and the K Dwarfs Draconis and HR 511 from Interferometric Measurements with the CHARA Array
Tabetha S. Boyajian, Harold A. McAlister, Ellyn K. Baines +13
Using the longest baselines of the CHARA Array, we have measured the angular diameter of the G5 V subdwarf Cas A, the first such determination for a halo population star. We co…
Taking the Measure of the Universe: Precision Astrometry with SIM PlanetQuest
Stephen C. Unwin, Michael Shao, Angelle M. Tanner +33
Precision astrometry at microarcsecond accuracy has application to a wide range of astrophysical problems. This paper is a study of the science questions that can be addressed usin…
The Solar Neighborhood. XIX. Discovery and Characterization of 33 New Nearby White Dwarf Systems
John P. Subasavage, Todd J. Henry, P. Bergeron +3
We present spectra for 33 previously unclassified white dwarf systems brighter than V = 17 primarily in the southern hemisphere. Of these new systems, 26 are DA, 4 are DC, 2 are DZ…
