WebIn stars with a convection zone just below the photosphere, the convective motions can generate acoustic waves that propagate upwards through the photosphere. The waves produce a wave pressure in the atmosphere that results in an additional force working against the stellar gravity. Cool stars have convection zones of this type but the ... Webthe basics. Convection is the transfer of internal energy into or out of an object by the physical movement of a surrounding fluid that transfers the internal energy along with its mass. Although the heat is initially transferred between the object and the fluid by conduction, the bulk transfer of energy comes from the motion of the fluid.
