What should the core mass fraction of a habitable planet that orbits very close to a dwarf star be to ensure electromagnetic protection from flares?

After reading this question, I became quite worried about my own habitable world with similar characteristics. Even worse, my star is presumably much younger -- only 8.787 Gyr (out of 50.207 Gyr). ...
