Scalar radiation from Chameleon-shielded regions

Understand

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, there is a resultant scalar radiation from the region of the source and the metric outside the spherically symmetric mass is not static.
• This has several interesting and potentially testable consequences.
