Star clusters are crucial objects for studying galaxy formation and evolution. However, analysis of star clusters within the disc of our Galaxy is limited due to interstellar extinction. Therefore, to understand evolution of star cluster systems in galaxy discs observations of nearby galaxies are needed. The best object for this purpose is the Andromeda (M31) galaxy, where ample of discovered star clusters enables us to study their impact on the evolution of stellar populations from the centre to the galaxy disc outskirts. In this work, we carried out multicolour aperture photometry and determined M31 star cluster parameters: age, mass, and interstellar extinction. Our results show that a major episode of star cluster formation in the present day north-eastern part of the M31 disc occurred ~200 Myr ago, while star cluster formation in the M31 16 kpc ring became prominent only recently (<40 Myr). We also find that the cluster mass function follows a truncated Schechter form, with a characteristic mass of 13300 solar masses. |
