The High Angular Resolution Multiplicity of Massive Stars
Brian D. Mason, William I. Hartkopf, Douglas R. Gies +2
We present the results of a speckle interferometric survey of Galactic massive stars that complements and expands upon a similar survey made over a decade ago. The speckle observat…
Direct Detection of the Close Companion of Polaris with the Hubble Space Telescope
Nancy Remage Evans, Gail H. Schaefer, Howard E. Bond +5
Polaris, the nearest and brightest classical Cepheid, is a single-lined spectroscopic binary with an orbital period of 30 years. Using the High Resolution Channel of the Advanced C…
Polaris: Mass and Multiplicity
Nancy Remage Evans, Gail Schaefer, Howard E. Bond +9
Polaris, the nearest and brightest classical Cepheid, is a member of at least a triple system. It has a wide () physical companion, the F-type dwarf Polaris B. Polaris itself…
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…
