The long-period variables in omega Centauri

Lebzelter, Thomas; Wood, Peter R

Description

Context. Recent studies have detected multiple populations in globular clusters. The massive globular cluster ω Cen hosts at least three populations of different metallicity. The most metal-rich one is thought to show also an overabundance of He. These differences should become visible in the structure, evolution, and pulsation of its stars. Aims. We aim to study the effects of the different starting compositions of the three populations in ω Cen on the most luminous red giants in this...[Show more]
