Abstract The star formation region CMa R1 corresponds to a late stage star forming region, with past explosions of massive stars sustaining the star formation currently moderately active today, with a low fraction of circumstellar discs, and with a population of young "old" stars of low mass coexisting with much younger objects. Several studies, performed at different wavelengths in this region, have shown that it is an excellent laboratory for the investigation of several factors that can interfere in the star formation, such as the influence of massive stars in their neighbourhood, in the past as well as in the present, and the presence of stars with discs in different evolutionary stages. Looking for to better understand the formation and early phases of the evolution of these objects, our group has developed theoretical studies of the physical processes related to the winds of stars of the solar-type and protostellar discs. In order to obtain observational links to these studies, we propose a pioneering multi-band analysis in this region, using data from the T80-Sul telescope (collaboration with the S-PLUS project), X-ray data, already studied by our group, and infrared (2MASS and WISE). With the set of filters available in the T80 (for example, H±, [OII], lines HK of Ca, among others) we will obtain data about the region of star formation (ionized gas distribution, magnetic activity, degree of turbulence, accretion rate circumstellar, etc.) in order to put links in the theoretical models proposed for the magnetic structure of stars in the Pre-Sequence Main and on the evolution of prostellar discs. | |
