Astrophysical Quantities of Cepheid Variables Measured with the Navy Prototype Optical Interferometer
We present mean angular diameters for two cepheid variables, alpha Ursae Minoris and zeta Geminorum, determined with the Navy Prototype Optical Interferometer (NPOI). We present linear radii for these cepheids and two additional cepheids, delta Cephei and eta Aquilae, previously observed at the NPOI. We find the limb-darkened angular diameter …
