In this work a density dependent quark model is revisited, its thermodynamic

consistency checked and the stability window for absolutely stable quark matter

obtained. The hypotheses of both pure quark matter with equal quark chemical

potentials and stellar matter subject to chemical stability and charge

neutrality are investigated. The parameters that appear in the density

dependent mass and satisfy the Bodmer-Witten conjecture are then used to

compute the masses and radii of strange stars. We show that the obtained values

are compatible with the recently observed massive stars.
