Description
High resolution (lambda/Δlambdaapprox.32,000) spectra have been obtained of the 2.3 μm CO Δupsilon = 2 region in two F Ia supergiants, HR 8752 and rho Cas. Both stars are known to have extensive circumstellar shells without infrared excesses, indicating circumstellar gas with little dust. The present spectra reveal strong CO Δupsilon = 2 lines of purely circumstellar origin at kinetic temperatures near 2000 K
