| Abstract: |
It is known that the location of the stars, from young open clusters to
large blue groups, follows fractal and sub-fractal patterns inherited from the original
molecular clouds in the star-forming process. In this work, we compared different mock
models and real observations. Also, for comparison purposes, we made mock models
of non-fractal cusp clusters using different parameters to describe the star density. We
also computed the Q parameter. This parameter describes the geometrical structure of
object distribution and statistically quantifies the fractal substructures, distinguishing
fragmented from smooth distributions. We also compared model realizations and real
observations in the same way. We presented the results of measuring the Q parameter
with different amounts of objects and levels of contamination by field stars. In this
way, we could understand the Q value behavior in poor stellar clusters and the impact
of the field stars. We compare and show a new algorithm that produces a circular
symmetry instead of the box-shape type commonly used to simulate fractal structures
in the astronomical context. |
