Interferometric determinations of asteroid diameters.
Abstract
New interferometric techniques are discussed with reference to asteroid studies. Speckle interferometry makes it possible to recover some information down to large telescope diffraction limits. A multiple-aperture amplitude interfermeter system allows the full telescope aperture to be covered simultaneously and all Fourier components sampled simultaneously. The new techniques make it possible to directly determine diameters of asteroids from earth-based observations. Results for some solar system objects are given. New possibilities include image reconstruction for asteroids and the detection of close asteroid pairs.
