    I assumed it would be further inward than the photon sphere because heat radiation is (also an assumption) easier for gravity to hold back than light. I don’t know how “heavy” a star’s heat is, though, so ¯\ˍ(ツ)ˍ/¯

      Heat radiation are particles with a mass and a certain speed, they are all by definition heavier and easier to trap than photons.

      In terms of escape velocity, nothing can try to escape faster than light.
