... So, anyone care to estimate the damage from going /into/ a star? :)
Found a possible starting point: 3e's Vehicles Expanion 1, and its formula for crush depth and test depth. Assuming that the wall shield pushes back against a star's matter, that it sticks close to the speedster's surface, and counts as an extra-heavy frame; and that every 11 yards of depth equates to a pressure of 14.5 psi; then the speedster's shield has a test depth that can handle a pressure of 234 gigapascals without a qualm, and a crush depth of 468 gigapascals.

What I haven't been able to find are any sources on pressures to be found inside a star, with one exception - that the centre of the sun is around 26,500 gigapascals. So at least we don't have to consider a speedster that can swim around throughout a star entirely unscathed. :)

The closest I've found to a depth-to-pressure chart is here, which is actually depth-to-density.


About the closest I've got to a plot-worthy result is something along the lines of "If you turn on a Bergenholm inertialess generator within a star's gravity well without turning on your drives, your ship is immediately drawn to its surface just as if the star had a tractor beam drawing you towards it. Your shields can resist the surface of the star's heat, light, and pressure for at least a couple of seconds, so make a skill roll to point your ship away from the star and turn on the drive before anything worse happens than the paint starts to singe..."
