Survey of infrared stars and planetary nebulae for circumstellar OH emission
With the 1000-ft Arecibo antenna we surveyed a total of 76 late-type stars, IRC and CRL infrared sources, and planetary nebulae in the 1612-, 1665-, and 1667-MHz lines of the OH molecule. OH was detected for the first time in eight objects, most of which are cool, evolved, giant stars. No planetary nebulae were detected nor were any stars previously classified or suggested to be either carbon rich or S type, including, for example, CRL 618, IRC+10216, BD30/sup 0/3639, chi Cyg, FG Sge, CRL 2688, CRL 3068, NGC 6572, and CRL 3099. High signal-to-noise spectra were obtained for some known OH maser stars such as NML Tau and IRC+10011.
