Astronomical results from COAST

摘要

Abstract: In September 1995 the Cambridge optical aperturesynthesis telescope (COAST) became the first opticalinterferometer to produce an image of a stellar sourcefrom phase-closure and visibility amplitudemeasurements. These observations demonstrated for thefirst time the feasibility of operating long-baselineopticalear-infrared interferometers for high dynamicrange high-resolution imaging. Here we present theseand subsequent observations made with COAST anddescribe the methods used to analyze such data. !16
