The spatial distribution of stars in open clusters
Nestor Sanchez, Emilio J. Alfaro
In this work we study the internal spatial structure of 16 open clusters in the Milky Way spanning a wide range of ages. For this, we use the minimum spanning tree method (the Q pa…
The Nature of the Gould Belt from a Fractal Analysis of its Stellar Population
N. Sanchez, E. J. Alfaro, F. Elias +2
The Gould Belt (GB) is a system of gas and young, bright stars distributed along a plane that is inclined with respect to the main plane of the Milky Way. Observational evidence su…
Fractal dimension of interstellar clouds: opacity and noise effects
Nestor Sanchez, Emilio J. Alfaro, Enrique Perez
There exists observational evidence that the interstellar medium has a fractal structure in a wide range of spatial scales. The measurement of the fractal dimension (Df) of interst…
Hierarchical Model for the Evolution of Cloud Complexes
Nestor Sanchez, Antonio Parravano
The structure of cloud complexes appears to be well described by a "tree structure" representation when the image is partitioned into "clouds". In this representation, the parent-c…
