Davis, J; North, J R; Robertson, James G; Tango, W J; Tuthill, Peter G; Ireland, Michael

Description

The Sydney University Stellar Interferometer (SUSI) has been used to make a new determination of the angular diameter of Sirius A. The observations were made at an effective wavelength of 694.1nm and the new value for the limb-darkened angular diameter is 6.048 ± 0.040 mas (±0.66%). This new result is compared with previous measurements and is found to be in excellent agreement with a conventionally calibrated measurement made with the European Southern Observatory's Very Large Telescope...[Show more]
