So in the sun's core, gamma rays are produced and right away, in the few milimetters, compton scattering happens.

As I understand the compton effect, gamma ray will first collide with free electron, and for the first collision, another gamma ray will be produced(from old one through scattering) - though this gamma ray will have a little bit longer wavelength(though, the difference in wavelengths are so small that new photon is still gamma ray. after so many scattering in the core, at some point, after x collisions, the photon will end up being x-ray.

Question 1: Is the above logic right ?

Question 2: do gamma rays escape the core and move into radiative zone ? or only some very small part of gamma rays reach radiative zone ? or all the photons that reach from core to radiative, they're already x-rays ?

    $\begingroup$ BTW, stellar fusion doesn't only release energy as gamma photons. A substantial amount of the energy is released as the kinetic energy of the fusion products. $\endgroup$

  • $\begingroup$ Well fusion itself only produces gamma rays in the sun’s core. Thats what everybody says. Though, due to compton scattering, you go to bigger wavelength photons. $\endgroup$ Commented May 1, 2023 at 13:46
  • $\begingroup$ Giorgi, only part of the fusion output energy is in the form of photons. I have some details (from Wikipedia) here: astronomy.stackexchange.com/a/48281/16685 $\endgroup$
