How do scientists gain a verifiable check on the computed temperature profiles of the Sun's core?

Answer

By observing neutrinos produced during core fusion

Neutrinos interact so weakly with matter that they stream directly out of the star’s core almost instantaneously, carrying a direct signature of the temperature and reaction rate occurring there, which confirms theoretical models.
