It has been recently proposed that very massive white dwarfs endowed with strongly
quantizing magnetic fields might be the progenitors of overluminous type Ia supernovae like
SN 2006gz and SN 2009dc. In this paper, we show that the onset of electron captures and
pycnonuclear reactions in these putative super-Chandrasekhar white dwarfs may severely
limit their stability.
