Scalar Radiation from Chameleon-Shielded Regions
I study the profile of the chameleon field around a radially pulsating mass. Focusing on the case in which the background (static) chameleon profile exhibits a thin shell, I add small perturbations to the source in the form of time-dependent radial pulsations. It is found that the chameleon field in...

| description | I study the profile of the chameleon field around a radially pulsating mass. Focusing on the case in which the background (static) chameleon profile exhibits a thin shell, I add small perturbations to the source in the form of time-dependent radial pulsations. It is found that the chameleon field inherits a time dependence and there is a resultant scalar radiation from the region of the source. This has several interesting and potentially testable consequences. |
