Stellar surface imaging using closure phase
Cavendish Laboratory, Cambridge, UK
We describe the use of interferometry to make images of features on the surfaces of cool stars. We describe observations of Betelgeuse (α Ori) and use this example to illustrate the requirements for astrophysical imaging with interferometers. We emphasise the importance of obtaining closure phase measurements and good Fourier plane coverage when imaging complex objects.
