Multi-wavelength observations of the red giant R Doradus with the MAPPIT interferometer
A. P. Jacob, T. R. Bedding, J. G. Robertson +4
We present visibility measurements of the nearby Mira-like star R Doradus taken over a wide range of wavelengths (650-990 nm). The observations were made using MAPPIT (Masked APert…

Interferometry and spectroscopy of Beta Cen: a Beta Cephei star in a binary system
J. G. Robertson, T. R. Bedding, C. Aerts +3
Beta Cen is a bright Beta Cephei variable and has long been suspected to be a binary. Here we report interferometric observations with the 3.9-m Anglo-Australian Telescope at a sin…
The angular diameter of R Doradus: a nearby Mira-like star
T. R. Bedding, A. A. Zijlstra, O. von der Luhe +4
We find the angular diameter of R Doradus to be 57 +/- 5 mas, exceeding that of Betelgeuse and implying that R Dor is larger in apparent size than every star except the Sun. R Dor…
An Optical Interferometer with Wavelength Dispersion
T. R. Bedding, J. G. Robertson, R. G. Marson
MAPPIT is an optical interferometer installed at the coude focus of the 3.9-m Anglo-Australian Telescope. The instrument combines non-redundant masking with wavelength dispersion a…
