Extinction by Gamma Ray Bursts

These equations of hydrostatic equilibrium allow us to calculate things like the density and temperature of the core, the way energy flows to the surface, and even the lifespan of stars. These models are largely built around what little we can learn from the light we receive directly from the surface of stars. But how do we test these models if we can never see beneath those surfaces? We may not see light from beneath the stellar surface, but another type of wave travels freely throughout stars. I’m talking about seismic waves.
