Period Changes as Evidence for Evolution in ω Cen

Conference paper
Part of the Astrophysics and Space Science Library book series (ASSL, volume 36)


Much has been said at this colloquium to the effect that observed changes in the periods of variable stars are so fast or so abrupt or so quick to change sign that they cannot possibly be attributed to stellar evolution. If you are wondering how this report can dare to make a contradictory claim read the title carefully. It does not promise that there really is evidence for evolution in Omega Centauri. It only proposes to look at the period changes with evolution in mind. We may all decide that the evidence is strong or that it is weak or perhaps that there is no evidence at all.
