Experiments for large multi-mirror telescopes. I.- Detection of non radial stellar oscillations.
Abstract
Preliminary measurements made with a 2-m telescope equipped with a sodium cell have shown that nonradial oscillations similar to the solar 5-min oscillations could be detected on bright stars with an integration time of three hours and a 5-m telescope. Because of their aberrations, large optical telescopes of the future will act as light collectors rather than imaging devices. An analysis demonstrates how interferometric techniques can be used to obtain good images with a multi-mirror telescope.
