The Search for Stellar Companions to Exoplanet Host Stars Using the CHARA Array
Ellyn K. Baines, Harold A. McAlister, Theo A. ten Brummelaar +4
Most exoplanets have been discovered via radial velocity studies, which are inherently insensitive to orbital inclination. Interferometric observations will show evidence of a stel…
Strong Near-Infrared Emission Interior to the Dust-Sublimation Radius of Young Stellar Objects MWC275 and AB Aur
