Evolution of S stars in the magellanic clouds
Published online by Cambridge University Press: 04 August 2017
Abstract
Early S stars occur between M and C stars in the colour magnitude diagrams of intermediate age globular clusters in the Magellanic Clouds. Most have −4.2 ≥ Mbol ≥ −4.8 and are probably brighter in younger or more metal rich clusters. The galactic globular cluster NGC 6723 contains two marginal S stars at Mbol ∼ −3.3. The rare CS stars have Mbol ∼ −6, with no faint examples.
