In this problem we will make a crude estimate of how the luminosity carton of a pulsating star s related to the variations in its radius. This provides a way of estimating the amount by which the radius is changing for a star that we observe to pulse. We will consider a star whose unperturbed state consists of a luminosity L0 a radius R0 and a surface temperature T0. ... see attached
