    "abstract": "We show that a hybrid (nuclear + quark matter) star can have a mass-radius\nrelationship very similar to that predicted for a star made of purely nucleonic\nmatter. We show this for a generic parameterization of the quark matter\nequation of state, and also for an MIT bag model, each including a\nphenomenological correction based on gluonic corrections to the equation of\nstate. We obtain hybrid stars as heavy as 2 M_solar for reasonable values of\nthe bag model parameters. For nuclear matter, we use the equation of state\ncalculated by Akmal, Pandharipande, and Ravenhall using many-body techniques.\nBoth mixed and homogeneous phases of nuclear and quark matter are considered.",
