The effect of including molecular opacities of variable composition on the evolution of intermediate-mass AGB stars

Fishlock, Cherie; Karakas, Amanda; Stancliffe, Richard

Description

Calculations from stellar evolutionary models of low- and intermediate-mass asymptotic giant branch (AGB) stars provide predictions of elemental abundances and yields for comparison to observations. However, there are many uncertainties that reduce the accuracy of these predictions. One such uncertainty involves the treatment of low-temperature molecular opacities that account for the surface abundance variations of C, N and O. A number of prior calculations of intermediate-mass AGB stellar...[Show more]
