Dynamical chameleon neutron stars: Stability, radial oscillations, and scalar radiation in spherical symmetry
Dynamical chameleon neutron stars: Stability, radial oscillations, and scalar radiation in spherical symmetry
Scalar-tensor theories whose phenomenology differs significantly from general relativity on large (e.g., cosmological) scales do not typically pass local experimental tests (e.g., in the Solar System) unless they present a suitable ``screening mechanism.'' An example is provided by chameleon screening, whereby the local general relativistic behavior is recovered in high-density …
