J/A+A/357/572       Dust formation in WC stars    (Cherchneff+, 2000)

Dust formation in carbon-rich Wolf-Rayet stars I. Chemistry of small carbon clusters and silicon species Cherchneff I., Le Teuff Y.H., Williams P.M., Tielens A.G.G.M. <Astron. Astrophys. 357, 572 (2000)> =2000A&A...357..572C
ADC_Keywords: Stars, Wolf-Rayet ; Stars, carbon ; Models, evolutionary Keywords: molecular data - molecular processes - stars: circumstellar matter - stars: Wolf-Rayet Description: The following table gives the ratefile of the chemical model. Columns α, β and γ give the rate k at temperature T in the Arrhenius form: k = α * (T/300)β * exp(-γ/T) The arrows indicate reversible reactions. File Summary:

Note (1): α is in units of cm6/s for thermolecular reactions (index = 1-27) and in units of s-1 for photo processes (index = 55-108). The rate k at temperature T is k = α * (T/300)β * exp(-γ/T) Note (2): References written in brackets as reactions refer to this reaction. The format has been contracted so that (X Y Z > T U) means: X + Y + Z --> T + U References with an 'E' have an estimated rate, a 'C' a rate calculated from cross sections.
