In this paper, we study the isentropic compressible planar magnetohydrodynamic equations with viscosity depending on density and with free boundaries. Precisely, when the viscosity coefficientλ(ρ) is proportional toρθwithθ> 0, whereρis the density, we establish the existence of global solutions under certain assumptions on the initial data by deriving some new a priori estimates.
