| Abstract: |
The Infrared Spatial Interferometer (ISI) has been conducting mid-IR measurements of
red supergiant and AGB stars for about 20 years. This paper reviews the
ISI system and results with an emphasis on measurements of
changes in stellar sizes and shapes, and those of the surrounding dust shells,
over time scales of weeks to decades. The long-term measurement record
provides important new observables for stellar theory.
A new spectrometer-correlator system is discussed where this system
will measure visibilities on-and-off individual molecular spectral lines. |
