  The work reported in this dissertation will concern the study of kinetics,
cycles and quantum mechanic processes of nuclear reactions involved in massive
stars together with explosive nucleosynthesis phenomena having a key role in
supernovae explosion. Four main fields will be explored: physics of nuclear
reaction, hydrogen burning, CNO cycles and explosive supernovae phenomena. The
first chapter will provide an overview of the background of the nuclear physics
and of the potential approaches to the field as quantum mechanic aspects, cross
section and Maxwell-Boltzmann distribution. The next chapter will describe the
hydrogen burning processes for stars with low mass (our sun), the CNO and hot
CNO cycles involved for higher mass stars and other cycles as sodium and
magnesium. The third chapter will review the helium burning process involved in
Red Giants as result of the exhausted hydrogen fuel. A short overview of other
helium processes will be briefly discussed. The fourth chapter will provide a
summary of the accepted model of explosive burning process involved in
supernovae explosion. Explosive nucleosynthesis together with heavy elements as
silicon burning processes will be also described.
