Most open clusters are made of young stars that formed in the active star-making regions of our galaxy's spiral arms. Results show that supermassive stars with 10$^3$ and 10$^4$ M$_\odot$ areĪlways formed due to the interplay of collisions and accretion, and in someĬases these objects are part of a binary system. Open clusters are left when a nebula such as Orion collapses, forms stars, then dissipates into space. Its evolution by performing $N$-body plus hydrodynamical simulations. Scale fragmentation during the collapse of a primordial gas cloud and follow Various properties of all the stars in a cluster are a function only of mass, and so stellar evolution theories rely on observations of open and globular clusters. The reason behind this is that almost all the stars in old clusters were born at roughly the same time. We model a small embedded cluster of accreting protostars following sub-parsec The dense star cluster called R136 is located within the Tarantula Nebula (also known as 30 Doradus), a giant star-forming region in a nearby dwarf galaxy. Star clusters are important in many areas of astronomy.
The interplay of collisions and accretion in star clusters at low metallicity. In this work we explore the problem of massive object formation due to It is however still uncertain if a supermassive star still emerges whenįragmentation occurs at smaller scales and a cluster of stars is formed $\sim10^$ and fragmentation is suppressed on pc scales. Numerical simulations have shown that supermassive stars can form inĪtomic-cooling halos when protostars reach accretion rates higher than The supermassive black holes powering the quasars observed in the early Intermediate step for the formation of the massive black hole seeds that become
