Introduction The envelope expelled by the carbon star CW Leo/IRC +10216 is remarkably rich in reactive species and in refractory com-pounds. Most of the stable metal-bearing molecules are ob-served fairly close the ...

In general, while differences remain between our model of IRC +10216 and the observed molecular column densities, better agreement is found between the calculated and observed radii of peak abundance.

WebThermally-pulsating AGB stars provide three-fourths of the matter returned to the interstellar medium. The mass and chemical composition of their ejecta largely control the chemical … WebThe initial observations of the prototype star IRC 10216 are confirmed by a survey of 8 C-rich AGB stars ( Neufeld et al., 2011 ). The high H 2 O temperature rules out comet … WebThe envelopes of AGB stars are irradiated externally by ultraviolet photons; hence, the chemistry is sensitive to the photodissociation of N$_2$ and CO, which are major reservoirs of nitrogen and carbon, respectively. The photodissociation of N$_2$ has recently been quantified by laboratory and theoretical studies. create a process flow in word
