Evolution of stellar magnetic activity and related phenomena

S. Messina and P. S. Parihar of Indian Institute of Astrophysics continued to study the evolution of angular momentum and magnetic activity of late-type stars. By using the 2-m HCT telescope of Indian Astronomical Observatory they have collected CCD photometry of late-type members in selected open stellar clusters of different ages and of T-Tauri stars in star forming regions. With the 1.3-m telescope of Skinakas observatory (Crete, Greece), S. Messina and K. Biazzo, in collaborarion with D. Hatzidimitriou of University of Crete, have carried out CCD photometric observations of the young open cluster NGC 7243.
