A survey of stellar families: multiplicity of solar-type stars
Deepak Raghavan,Harold A. McAlister,Todd J. Henry,David W. Latham,Geoffrey W. Marcy,Brian D. Mason,Douglas R. Gies,Russel White,T. ten Brummelaar +8 more
TL;DR: In this article, the authors present the results of a comprehensive assessment of companions to solar-type stars, including the Sun, from the Hipparcos catalog with {pi}>40 mas, {sigma}{sub {pi/{pi}} < 0.05, 0.5 {<=} B - V {< =} 1.0 ({approx}F6-K3), and constrained by absolute magnitude and color to exclude evolved stars.
Journal ArticleDOI
Spitzer IRAC Photometry of M, L, and T Dwarfs
Brian M. Patten,John R. Stauffer,Adam Burrows,Massimo Marengo,Joseph L. Hora,Kevin Luhman,Kevin Luhman,Sarah Sonnett,Sarah Sonnett,Todd J. Henry,Deepak Raghavan,S. Thomas Megeath,James Liebert,Giovanni G. Fazio +13 more
TL;DR: In this paper, the results of a program to acquire photometry for 86 late M, L, and T dwarfs using the Infrared Array Camera (IRAC) on the Spitzer Space Telescope were presented.
Journal ArticleDOI
Two Suns in The Sky: Stellar Multiplicity in Exoplanet Systems
Deepak Raghavan,Todd J. Henry,Brian D. Mason,John P. Subasavage,Wei-Chun Jao,Thom Beaulieu,Nigel Hambly +6 more
TL;DR: In this paper, the authors present results of a reconnaissance for stellar companions to all 131 radial velocity-detected candidate extrasolar planetary systems known as of 2005 July 1, and confirm that a lower limit of 30 (23%) of the 131 exoplanet systems have stellar companions.

A Survey of Stellar Families: Multiplicity of Solar-Type Stars
Deepak Raghavan,Harold A. McAlister,Todd J. Henry,David W. Latham,Geoffrey W. Marcy,Brian D. Mason,Douglas R. Gies,Russel White,T. ten Brummelaar +8 more
TL;DR: In this article, the authors presented the results of a comprehensive assessment of companions to solar-type stars, including the Sun, from the Hipparcos catalog with a sample of 454 stars including the sun, and showed that only a few undiscovered companions remain in this well-studied sample.
Journal ArticleDOI
Angular Diameters of the G Subdwarf μ Cassiopeiae A and the K Dwarfs σ Draconis and HR 511 from Interferometric Measurements with the CHARA Array
Tabetha S. Boyajian,Harold A. McAlister,Ellyn K. Baines,Douglas R. Gies,Todd J. Henry,Wei-Chun Jao,David P. O'Brien,Deepak Raghavan,Y. Touhami,T. ten Brummelaar,Chris Farrington,P. J. Goldfinger,Laszlo Sturmann,Judit Sturmann,Nils H. Turner,Stephen T. Ridgway +15 more
TL;DR: In this paper, the angular diameter of the G5?V subdwarf (Cas?A) was measured using the longest baselines of the CHARA Array, the first such determination for a halo population star.
