On the Brightest Horizontal Branch Population II Star γ Piscium.

FUHRMANN K. and CHINI R.

Abstract (from CDS):

The bright star γ Psc is among the nearest Population II giants located in the red clump region. Here we demonstrate that γ Psc is actually a core-helium burning horizontal branch star. As such, the τ ≃ 12 Gyr old γ Psc is found to be slightly over-massive at MHB = 0.97 ± 0.12 M⊙, which suggests that it is possibly a rejuvenated source.
