Astrometry - Challenging our Understanding of Stellar Structure and Evolution
G. Fritz Benedict, Todd J. Henry, Rob Olling
Stellar mass plays a central role in our understanding of star formation and aging. Stellar astronomy is largely based on two maps, both dependent on mass, either indirectly or dir…
Ground-Based Astrometry 2010-2020
Todd J. Henry, David G. Monet, Paul D. Shankland +3
We discuss the opportunities for astronomical discovery via ground-based astrometry carried out in the United States during the 2010-2020 decade. We describe imminent scientific br…
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…
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…
Identifying and Characterizing New Nearby White Dwarfs
John P. Subasavage, Todd J. Henry, Pierre Bergeron +3
How confident are we that all of the nearest white dwarfs (WDs) have been identified? In an effort to answer this question, we have begun an initiative to identify and characterize…
Discovery of Two T Dwarf Companions with the Spitzer Space Telescope
K. L. Luhman, B. M. Patten, M. Marengo +12
We report the discovery of T dwarf companions to the nearby stars HN Peg (G0V, 18.4 pc, ~0.3 Gyr) and HD 3651 (K0V, 11.1 pc, ~7 Gyr). During an ongoing survey of 5'x5' fields surro…
