We present positions and magnitudes of stars and star clusters in a 1° × 1° area centered on M33. The survey is based on deep archival ground-based images using...

We present observations for three star clusters, Kron 11, Kron 63 and NGC 121, in the Small Magellanic Cloud. We have studied their structure and derived their...

Massive stars in young massive clusters insert tremendous amounts of mass and energy into their surroundings in the form of stellar winds and supernova ejecta...

An observational test of the binary hypothesis for the origin of blue straggler stars is conducted by searching for radial velocity variables among 30 blue...

Context. The chemical composition of young massive clusters (YMCs) provides stellar population information on their host galaxy. As potential precursors of...

The process of chemical self-enrichment in stellar systems can be affected by the total mass of the system and the conditions of the large-scale environment...

We present a short summary of several 2D hydrodynamic calculations that suggest that upon the collision of galaxies two physical mechanisms lead to the...

We present photometric and morphological analyses of nuclear star clusters (NSCs)-very dense, massive star clusters present in the central regions of most...

Context. Nuclear star clusters (NSCs) are found in at least 70% of all galaxies, but their formation path is still unclear. In the most common scenarios, NSCs...
