Lunar occultations and long-baseline interferometry are two direct observational methods capable of delivering milliarcsecond resolution of binary stars. We will review the status of these two techniques, particularly with reference to their respective advantages, limitations, and accessibility for binary star research programs. We will also illustrate the near-term prospects, in connection with the availability of large modern interferometric facilities such as the VLTI.

Resumen

Resumen

Las ocultaciones lunares y la interferometría de gran base son dos métodos directos de obsevación capaces de lograr resoluciones de milisegundos de arco para estrellas binarias. Examinamos el estado actual de estas dos técnicas y, en particular, sus ventajas y desventajas, sus limitaciones y su accesibilidad para programas de investigación sobre binarias. También examinamos las perspectivas a corto plazo en relación a la disponibilidad de instrumentos interferométricos grandes como el VLTI.
