             abstract = "We revisit the properties of relativistic and quantum complex 
                         systems of massive white dwarfs (WDs) using a modern equation of 
                         state (EoS) which accounts for electron-ion interactions among 
                         lattice nuclei, and which makes use of the latest experimental 
                         atomic mass data. We estimate the mass density thresholds for the 
                         onset of nuclear reactions in the cores of massive WDs and study 
                         the impact of microscopic stability on the structure and stability 
                         of different WD constitutions. We focus on the properties of 
                         massive carbon and oxygen white dwarfs, taking into account the 
                         electron capture and pycnonuclear fusion reactions instabilities. 
                         Our results indicate that pycnonuclear reactions turn carbon WDs 
                         unstable while for oxygen WDs their instability is due to the 
                         inverse beta -decay (electron capture) process. We highlight that 
                         these dynamical nuclear processes are of great relevance for 
                         assessment of stability of these quantum complex systems of 
                         massive WDs, since they constrain their maximum masses.",
