Abstract

This project aims to insert the student in an interesting and relevant subject that is star formation. It uses the experience of involved researchers and, especially, the new reality of observational data dictated by the second release of Gaia space mission, complemented with others from literature. The focus is the Chamaeleon molecular cloud complex and its star formation history. Within the scope of this project, we must accomplish a survey of stars in the Chamaeleon star-forming region including various subgroups (Cha I, Cha II, eta Cha and epsilon Cha), to obtain astrometric, photometric and spectroscopic parameters of each object from published data, and characterize spatial and kinematic structure of each subgroup of Chamaeleon complex. In the development of the project, Drs. P. Galli and C. Ducourant of "Laboratoire d'Astrophysique de Bordeaux" will collaborate with us. This work can be easily extended: a study of a possible relation between two closest groups (eta Cha and epsilon Cha) and the furthest (Cha I and Cha II) and, thus, with the Chamaeleon cloud complex; new members, especially those low-mass and sub-stellar populations. These subjects can be covered from an undergraduate level, as well with further deepening, opening good views to an academic career in this area.
