Scientific paper

The authors report the first detection of HCN in the oxygen-rich evolved
star IRC +10420. This star has been classified as an F8 supergiant and
is considered by many to be in transition between a red giant star and a
planetary nebula. Its circumstellar envelope may be in a more advanced
stage of chemical evolution than red giant envelopes.
