Fractal dimension in star formation regions
Canavesi Tobias, Hurtado Santiago
TL;DR
This paper introduces a method to calculate the 3D fractal dimension of star formation regions using Gaia data, providing new insights into their spatial distribution beyond previous 2D analyses.
Contribution
It presents a novel approach to directly compute the 3D fractal dimension of star-forming regions using Gaia data, avoiding projection distortions.
Findings
Fractal dimensions of regions range from 2.126 to 2.468.
The method confirms fractal distribution of star formation regions in 3D.
Provides new quantitative measures of star formation spatial structure.
Abstract
Several two-dimensional studies in spiral galaxies show that HII star formation regions have a fractal distribution, with a fractal dimension of approximately 2.3. In this work, the fractal dimension is calculated through the box-counting method implemented in an R code. The innovation of the work lies in calculating the fractal dimension directly in 3 dimensions, without the need for the use of projections, using position and distance data from Gaia (Data version 2). The estimated fractal dimension for the regions studied in the Milky Way are 2.468 (M16), 2.126 (Orion Nebula) and 2.435 (RCW 38).
