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…
Stability of thermal structures with an internal heating source
Nestor Sanchez, Eugenio Lopez
We study the thermal equilibrium and stability of isobaric, spherical structures having a radiation source located at its center. The thermal conduction coefficient, external heati…
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…
