Spitzer/IRAC Photometry of M, L, and T Dwarfs
Brian M. Patten, John R. Stauffer, Adam Burrows +9
We present the results of a program to acquire photometry for eighty-six late-M, L, and T dwarfs using the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. We examine t…
The Visual Orbit of the 1.1-day Spectroscopic Binary Ï^2 Coronae Borealis from Interferometry at the CHARA Array
Deepak Raghavan, Harold A. McAlister, Guillermo Torres +11
We present an updated spectroscopic orbit and a new visual orbit for the double-lined spectroscopic binary Ï^2 Coronae Borealis based on radial velocity measurements at the Oak Ri…
Speckle Interferometry of Red Dwarf Stars
Brian D. Mason, William I. Hartkopf, Korie N. Miles +3
We report high resolution optical speckle observations of 336 M dwarfs which result in 113 measurements of relative position of 80 systems and 256 other stars with no indications o…
Know the Star, Know the Planet. II. Speckle Interferometry of Exoplanet Host Stars
Brian D. Mason, William I. Hartkopf, Deepak Raghavan +4
A study of the host stars to exoplanets is important to understanding their environment. To that end, we report new speckle observations of a sample of exoplanet host primaries. Th…
A Survey of Stellar Families: Multiplicity of Solar-Type Stars
Deepak Raghavan, Harold A. McAlister, Todd J. Henry +6
We present the results of a comprehensive assessment of companions to solar-type stars. A sample of 454 stars, including the Sun, was selected from the Hipparcos catalog with Ï >…
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…
Spectroscopy, MOST Photometry, and Interferometry of MWC 314: Is it an LBV or an interacting binary?
Noel D. Richardson, Anthony F. J. Moffat, Raphaël Maltais-Tariant +34
MWC 314 is a bright candidate luminous blue variable that resides in a fairly close binary system, with an orbital period of 60.7530.003 d. We observed MWC 314 with a combinat…
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 c…
