nfrared spectra of
Mira-type variables were obtained from a NASA Lear Jet in February, 1977,
flying at an altitude of 13.7 km. At this altitude less than 1% of the earth's
water vapor remains above the telescope and hence the entire near-infrared
spectrum of these very red stars is seen unobscured. This observational Program
could not be conducted without the assistance of the AAVSO which provided
visual magnitude predictions for these variables, which vary from 6th to 13th
magnitudes. For a given observing date it is most important to know bright a particular
variable will be as there is only a limited observing time possible each
flight. A folded 12-inch telescope of Dall-Kirkham design was used for these
observations. The infrared spectrum of Mira (o Ceti) and the "hot"
water bands and carbon monoxide (CO) features are discussed.
