Abstract
We present the basic theory of nuclear reactions in stars and sketch
the general rules of stellar evolution. Then we shortly review the
subject of supernova explosions both by core collapse in massive
stars (type II) and carbon-deflagration in binary systems when one
of the components is a White Dwarf accreting mass from the companion
(type Ia). We also present elementary notions of s- and r-process
nucleo-synthesis. Finally, we shortly review the topic of galactic
chemical evolution and highlight some simple solutions aimed at
understanding the main observational data on abundances and
abundance ratios.
