Quantitative Stellar Spectral Classification. IV. Application to the Open Cluster IC 2391
J. García, N. Sánchez, R. Velásquez
In this work we perform the first test of a stellar spectral classification method (Stock & Stock 1999) by applying it to early type stars. The sample of stars are the members of t…
The Fractal Distribution of HII Regions in Disk Galaxies
Nestor Sanchez, Emilio J. Alfaro
It is known that the gas has a fractal structure in a wide range of spatial scales with a fractal dimension that seems to be a constant around Df = 2.7. It is expected that stars f…
Determining the Fractal Dimension of the Interstellar Medium
Nestor Sanchez, Emilio J. Alfaro, Enrique Perez
The Interstellar Medium seems to have an underlying fractal structure, which can be characterized through its fractal dimension (Df). However, several factors may affect the determ…
On the properties of fractal cloud complexes
Nestor Sanchez, Emilio J. Alfaro, Enrique Perez
We study the physical properties derived from interstellar cloud complexes having a fractal structure. We first generate fractal clouds with a given fractal dimension and associate…
The Fractal Dimension of Projected Clouds
Nestor Sanchez, Emilio J. Alfaro, Enrique Perez
The interstellar medium seems to have an underlying fractal structure which can be characterized through its fractal dimension. However, interstellar clouds are observed as project…
