  We consider the possibility of having hybrid stars with a phase transition
from hadrons into strange matter at the core of a neutron star in b
equilibrium. For the hadron phase equation of state (EoS) the quark-meson
coupling model is used, while the MIT bag model is used to describe the strange
matter phase. The phase transition is treated using the Gibbs construction
method and results are calculated and checked against the observational
constaints imposed on the EoS. The results are also compared with the hadronic
EoS including hyperons, F-QMC700
