We discuss the implications on the future evolution of planetary systems orbiting red giant stars, if physical reactions involving the production of axions and the enhanced decay of plasmons into neutrinos, as a consequence of neutrinos having a magnetic dipole moment, are assumed to be happening simultaneously within the stellar core. Simulations were created by employing a numerical code to calculate the physical properties of stellar models from the main sequence to the end of the red giant phase, for stars with a mass range between 0.9 and 1.9 M and we analyze the most noticeable differences to canonical stellar evolution. Two exoplanet systems, known for harboring single red giant stars, were modelled by using the predicted stellar properties to calculate the temporal variation of the habitable zone and the orbital distance.
