Web14 Nov 2008 · 6. Janus said: As to why the Sun's luminosity increases with time: As the Sun fuses hydrogen, the core begins to become "clogged up" with helium "ash", which would tend to damp out the fusion reaction. The helium ash also increases the density of the core. The result is that the temp and pressure goes up which increases the fusion rate which ...
