Abstract: We generalize the Bogoliubov quark-meson coupling (QMC) model to also include hyper- ons. The hyperon-σ-meson couplings are fixed by the model and the hyperon-ω-meson couplings are fitted to the hyperon potentials in symmetric nuclear matter. The present model predicts neutron stars with masses above 2M⊙ and the radius of a 1.4M⊙ star ∼14 km. In the most massive stars, bags overlap at the core of the star, and this may be interpreted as a transition to deconfined quark matter.
