This problem illustrates the concept of the Eddington luminosity of a star. The Eddington luminosity is that luminosity at which the radiation pressure at the photosphere matches the hydrostatic pressure of the atmosphere. As stars get more massive they can become hot enough to reach and even the Eddington luminosity. When that happens, they can blow away their outer layers. This problem offers a heuristic illustration of this effect under the assumption of a very simple opacity law. (a) Consider the outer layers of a star, near the photosphere. The dominant contribution to the pressure is radiation pressure. The star is in hydrostatic equilibrium and outward heat transport is accomplished by radiative diffusion. Show that, under these conditions the luminosity of the star is related to its mass and the opacity by $L_* = L_{Edd} = \frac{4\pi c G M_*}{\kappa}$ (6) (b) Assuming that the opacity near the photosphere is dominated by electron scattering (in a fully-ionized gas), $\kappa = \kappa_e = 0.4 \text{ cm}^2 \text{ g}^{-1}$, find the minimum mass of a star that exceeds the Eddington limit. (c) In the same spirit as above, assuming that the opacity near the photosphere can be parameterized in terms of the temperature as $\kappa = 1.3 \times 10^{16} T^{-7/2} \text{ cm}^2 \text{ g}^{-1}$ (where $T$ is in Kelvin), find the minimum mass of a star that exceeds the Eddington limit.
