Twenty-eight angular diameters for late-type stars by the lunar occultation technique.

Abstract

New angular diameter measurements obtained with an infrared photometer are reported. The stars observed include three Mira variables and nine cool IRC objects. Repeat measurements are reported for five stars. The observations include numerous daytime and reappearance events. Several results obtained with the 4-m telescope verify the value of a large aperture for the measurement of angular diameters as small as 1.5-2.5 milliarcsec.
