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 XVII: Parallax Results from the CTIOPI 0.9m Program -- Twenty New Members of the RECONS 10 Parsec Sample
Todd J. Henry, Wei-Chun Jao, John P. Subasavage +4
Astrometric measurements for 25 red dwarf systems are presented, including the first definitive trigonometric parallaxes for 20 systems within 10 pc of the Sun, the horizon of the…
Two Suns in The Sky: Stellar Multiplicity in Exoplanet Systems
Deepak Raghavan, Todd J. Henry, Brian D. Mason +4
We present results of a reconnaissance for stellar companions to all 131 radial-velocity-detected candidate extrasolar planetary systems known as of July 1, 2005. CPM companions we…
Ages of White Dwarf-Red Subdwarf Systems
Hektor Monteiro, Wei-Chun Jao, Todd Henry +2
We provide the first age estimates for two recently discovered white dwarf-red subdwarf systems, LHS 193AB and LHS 300AB. These unusual systems provide a new opportunity for linkin…
The Massive Runaway Stars HD 14633 and HD 15137
T. S. Boyajian, T. D. Beaulieu, D. R. Gies +6
We present results from a radial velocity study of two runaway O-type stars, HD 14633 (ON8.5 V) and HD 15137 (O9.5 III(n)). We find that HD 14633 is a single-lined spectroscopic bi…
The Solar Neighborhood X: New Nearby Stars in the Southern Sky and Accurate Photometric Distance Estimates for Red Dwarfs
Todd J. Henry, John P. Subasavage, Misty A. Brown +3
Photometric VRI and spectroscopic (6000-9500 A) observations of high proper motion stars discovered during the first phase of the SuperCOSMOS RECONS (SCR) search are used to estima…
