Abstract
In this work, we review photometric, kinematic and chemical properties of the minor merger systems, in order to better understand of the effects that interaction may play on the evolution of their components. Despite their importance, the minor mergers have been less studied than major merger interactions. However, minor mergers are recognized as potential agents to drive the galactic evolution. The interaction with a small companion can generate all kinds of phenomena seen in major cases, such as tidal tails, bridges, rings, as well as the formation or destruction of bars or spiral arms, and triggering the star formation. One of the main effects is the loss of angular momentum of the gas due to the torque exerted by the small companion galaxy. This results in a significant amount of gas inflows into the inner part of the disk and the nuclear region. As consequence, the chemical elements can be stirred up affecting their distribution and metallicity gradient and/or feed nuclear activity. In addition, the velocity field of the main galaxy often shows asymmetries and irregularities due to the interaction with the smaller companion.
