Understanding the Chemical Complexity in Circumstellar Envelopes of C-rich AGB Stars: the Case of IRC +10216
M. Agundez, J. Cernicharo, J. R. Pardo +5
The circumstellar envelopes of carbon-rich AGB stars show a chemical complexity that is exemplified by the prototypical object IRC +10216, in which about 60 different molecules hav…
Detection of Near-IR CO Absorption Bands in R Coronae Borealis Stars
Emily D. Tenenbaum, Geoffrey C. Clayton, Martin Asplund +8
R Coronae Borealis (RCB) stars are hydrogen-deficient, carbon-rich pulsating post-AGB stars that experience massive irregular declines in brightness caused by circumstellar dust fo…
An Extremely Large Excess of 18O in the Hydrogen-Deficient Carbon Star, HD 137613
Geoffrey C. Clayton, Falk Herwig, T. R. Geballe +4
We report the discovery of a uniquely large excess of 18O in the hydrogen-deficient carbon (HdC) star, HD 137613, based on a spectrum of the first overtone bands of CO at 2.3-2.4 m…
