Abstract

Optical and infrared interferometers operating with high spectral resolution can provide velocity-resolved information on the milliarcsecond and sub-milliarcsecond scale. This enables completely new observational approaches to many open problems in stellar and circumstellar astrophysics. Fiber coupling of the output from a relatively simple beam combiner to existing spectrographs offers a cost-effective way to implement interferometric high-resolution spectroscopy at the European Southern Observatory's Very Large Telescope Interferometer.
