After core helium burning in low and intermediate-mass stars, starts the AGB phase. In this phase, the s process takes place, which is believed to be at the origin of half of all elements heavier than iron. The role of rotation and magnetic fields on...

Wolf-Rayet (WR) stars, as they are advanced stages of the life of massive stars, provide a good test for various physical processes involved in the modelling of massive stars, such as rotation and mass loss. In this paper, we show the outputs of the... Read More about Wolf-Rayet stars as an evolved stage of stellar life.

Conference Proceeding
Taylor. (2012). Eclipsing Binary Stars: the Royal Road to Stellar Astrophysics. In Proceedings of the workshop "Orbital Couples: Pas de Deux in the Solar System and the Milky Way" (51-58)

Russell (1948) famously described eclipses as the "royal road" to stellar astrophysics. From photometric and spectroscopic observations it is possible to measure the masses and radii (to 1% or better!), and thus surface gravities and mean densities,...
