ADC_Keywords: Planets ; Interferometry ; Infrared sources ; Stars, double and multiple Keywords: infrared: stars - planetary systems - stars: fundamental parameters - techniques: interferometric Abstract: We have measured the angular diameters for a sample of 24 exoplanet host stars using Georgia State University's CHARA Array interferometer. We use these improved angular diameters together with Hipparcos parallax measurements to derive linear radii and to estimate the stars' evolutionary states. Description: We obtained data on 24 exoplanet (stars needed to be brighter than V=+10 in order for the tip/tilt subsystem to lock onto the star, and brighter than K=+6.5 so that fringes were easily visible) over multiple observing runs spanning 2004 January to 2007 September (see Table 1). The stars were observed using the Center for High Angular Resolution Astronomy (CHARA) Array, a six-element Y-shaped interferometric array located on Mount Wilson, California. File Summary:
