The stellar rotation undergoes several changes during the whole stellar life. Such changes depend e.g., on the evolution of the internal structure, angular momentum, magnetic field etc. Our knowledge on the rotation properties at different stellar ages is increasing, however, much still to be done as the number of variables discovered in star clusters are not sufficiently large enough to constrain the various models proposed to describe the mechanisms that drive the angular momentum evolution, disk evolution etc. Specifically, the variables are not well distributed over age sequence and there are vital gaps in the age sequence of the sample of available periodic cluster members. The relationship between age, rotation, and activity has been a crucial topic of stellar evolution over the last several years. The determination of stellar rotational periods in large samples of stars of different ages and mass is also crucial for understanding the relationships with stellar properties and their close surrounding. We are studying variability in stellar objects in young star forming regions to understand those different physical processes. |
