A New Michelson Stellar Interferometer

  • R. Q. Twiss (a1) and W. J. Tango (a1)

Abstract

A new 1.87 m fixed-baseline interferometer designed for binary star observation is now in operation at the Italian outstation of the Royal Observatory Edinburgh. It has a theoretical resolving power of 0.015 arcsee and a limiting B magnitude of 6.5. Atmospheric seeing is dynamically corrected, allowing a quantitative measurement of fringe visibility.

Resumen

Un nuevo interferòmetro con 1.87 m de línea de base fija, diseñado para observaciones de estrellas binarias está ahora en operación en la estación italiana del Observatorio Real de Edinburgo. Este equipo tiene un poder de resolución teórico de 0.015 seg. de arco y una magnitud B límite de 6.5. Se ha corregido dinámicamente el “seeing” atmosférico, permitiendo así, una medición cuantitativa de la visibilidad de franjas.
