Gravity's Rainbow and Compact Stars
  A number of recent studies has focused on the implications of new physics at the Planck scale on the equilibrium of compact astrophysical objects such as white dwarf and neutron stars. Here we analyze the modification of the equilibrium configurations induced by the so-called Gravity's Rainbow that account for Planck scale deformation of the space-time.
