Some aspects about laboratory cometary models

During the past decades, astronomers have directed their attention toward the study of the solar system bodies, like comets, and they have made many discoveries. These studies have provided profound insights into the formation and earliest story of the solar system. A complementary role in the study of comets has been played by laboratory research on cometary models. In this paper, we discuss some aspects of laboratory experiments proposed in the literature, specially those associated with the chemical reactions that may occur in the comets. These comments are made the light of chemical composition, energy source, relevant chemical reactions and compounds detected in several laboratory simulations of cometary material. (author).
