Description

We discuss the physics of p-modes travelling though the atmospheres of A stars. We show how the fluctuations in opacity affects the perturbations in flux and discuss the new formulae we derived that relates the flux perturbations to temperature and opacity perturbations. Our new formula is compared with other formulae that have been used in the studies of the p-modes
