My question has to do with the following two pieces of information:

  1. When Fusion Ignites and a star is born, according to the Proton-Proton Chain, a positron and a neutrino are released when one proton undergoes beta+ decay and becomes a neutron.

  2. "The mass of an atomic nucleus is less than the sum of the individual masses of the free constituent protons and neutrons (according to Einstein's equation E=mc2) and this 'missing mass' is known as the mass defect, and represents the energy that was released when the nucleus was formed." https://en.m.wikipedia.org/wiki/Nuclear_binding_energy#Mass_defect

My question is this: is the excess energy of the mass defect added to the positron and neutrino?

My guess is yes, but I'm not entirely sure.

Yes, the energy is transferred to the kinetic energy of the particles that are produced.
