TL;DR
This study uses the CHARA Array interferometer to measure the angular diameters of 24 exoplanet host stars, improving their physical parameter estimates and understanding their evolutionary stages.
Contribution
It provides precise angular diameter measurements for exoplanet host stars, enhancing stellar characterization methods.
Findings
Accurate stellar radii derived from interferometry and parallaxes.
Improved understanding of the evolutionary states of host stars.
Enhanced data for exoplanet characterization.
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.
