The Case of the Carbon Star Mystery
Institute of Astronomy,
University of Cambridge, UK
The well-determined distances to the Large and Small Magellanic Clouds allow us to construct luminosity functions for carbon stars in these populations, affording an excellent opportunity to test stellar evolution models of asymptotic giant branch (AGB) stars undergoing third dredge-up. However, since the earliest days of the modelling of AGB stars, the models have failed to be able to reproduce these luminosity functions. I will discuss new results calculated with the Cambridge evolution code (STARS) and how they relate to calculations with other state-of-the-art codes.
