Can I read HCN in the inner envelope of {chi} Cygni on EtoBox?

HCN in the inner envelope of {chi} Cygni by Duari, Debiprosad; Hatchell, Jennifer is a scholarly article available to read on EtoBox.

What is HCN in the inner envelope of {chi} Cygni about?

We have detected the (0,11c,0)J=3-2 and (0,0,0)J=8-7 transitions of HCN towards the S star {chi} Cygni. The excitation requirements of these transitions are too high to be satisfied in the outer envelope of the star, and the emission must originate within {solar}20 stellar radii, ie. the molecule must be forming close to the star. This conclusion is supported by a model for AGB stars in which molecules including HCN form in a shocked wind close to the stellar surface.
