A new hybrid star model in Krori-Barua spacetime

Present paper provides a new model of hybrid star with strange quark matter along with normal baryonic matter. The relation between pressure and density of the quark matter is given by the MIT bag model equation of state. The model is developed in the framework of Krori and Barua (KB) ansatz (Krori and Barua, Phys. A, Math. Gen. 8:508, 1975). All the physical requirements are satisfied by our model. The value of mass calculated from our model is close to the observational data which gives the validity of our present model. We match our interior solution to the exterior Schwarzschild metric where negative surface pressure is required to hold the thin shell against collapsing.
