On the period distribution of cluster RR Lyrae stars to constrain their helium content: the case of omega Centauri

Marcella Marconi, Giuseppe Bono, Filippina Caputo +3

We present new sets of nonlinear, time-dependent convective hydrodynamical models of RR Lyrae stars assuming two metal (Z=0.0005, Z=0.001) and three helium abundances (Y=0.24, 0.30…
