My professor gave us a question to think about for discussion next week. He asked how the radius of a star, who is composed of ionized hydrogen and degenerate electrons, varies with mass. I am not quite sure where to start. How could I estimate the radius?

Your professor is asking a question that requires you to consider hydrostatic equilibrium.

If the pressure support is degenerate electrons then you are talking about "electron degeneracy pressure"

That might be a place to start.

You might find these two links helpful as well.
