Constraints on Modified Gravity Models from White Dwarfs
  Modified gravity theories can introduce modifications to the Poisson equation
in the Newtonian limit. As a result, we expect to see interesting features of
these modifications inside stellar objects. White dwarf stars are one of the
most well studied stars in stellar astrophysics. We explore the effect of
modified gravity theories inside white dwarfs. We derive the modified stellar
structure equations and solve them to study the mass-radius relationships for
various modified gravity theories. We also constrain the parameter space of
these theories from observations.
