description: The subject of the graduate qualification work is ''Simulation of physical processes in compact clusters of young massive stars''
Young massive star clusters connect many branches of astrophysics. These objects have extreme properties, as they have a stellar density that is several orders of magnitude higher than that typical of known stellar associations. The study of young massive clusters is of particular interest in solving the fundamental problem of stellar formation in various cosmological epochs. They are also a powerful natural laboratory for studying the evolution of massive stars.
The importance of such clusters is largely due to the content of a great number of massive stars that have a huge impact on their environment. The presence of dozens of young hot stars, including Wolf-Rayet type stars, in an area of the order of parsec size raises the problem of a detailed simulation of the interaction of multiple stellar winds accelerated by the radiative force of hot massive stars.
In this work, using the well-proven PLUTO code, we performed three-dimensional MHD simulation in order to study the dynamics of the interaction of the stellar winds of young massive stars in a compact super star cluster at a scale of 1 parsec, which allowed us to resolve in detail the resulting structure of flows and magnetic fields.
As a result, we obtained detailed maps of densities, flow velocities, and temperatures in the inner regions of the super star cluster, where a complex flow structure is observed. Brand new results are the constructed 3D and 2D maps of the magnetic field, revealing both its complex structural features and characteristic magnitudes. It is shown that the powerful winds of Wolf-Rayet stars determine the dynamics and global structure of currents.
