Esta investigación busca comparar distintos métodos de cálculo de distancias con el fin de determinar la distancia a la Gran Nube de Magallanes LMC. Se establece esta distancia ($d_{LMC}$) usando: paralaje estelar, estrellas variables de tipo RR Lyrae y cefeidas clásicas, corrimiento a rojo y mecánica celeste; de los cuales se determina el error sistemático y error estándar de cada uno. Finalmente, tras el análisis de cada método, se obtiene un resultado de $d_{LMC}$ = 50.4802 $±0.0638_{std}$ $±0.0638_{sys}$ alejado por +0.5102 Kpc del valor aceptado actualmente de $d_{LMC}$ = $49.97$ Kpc (Pietrzyński., et al, 2014)., este valor se obtuvo combinando las distancias halladas mediante los métodos de variables RR Lyrae, variables cefeidas clásicas y la supernova SN1987a.

Abstract

This research paper looks foward to compare different methods to calculate the distance to the Large Magellanic Cloud LMC. The distance $d_{LMC}$ is calculated using: stellar parallax, variable stars: RR Lyrae and Classical Cepheids, redshift and celestial mechanics; from which the systematic error and standard error is determined. Finally, after the analysis of each method, the distance is obtained being set at $d_{LMC}$ = 50.4802 $±0.0638_{std}$ $±0.0638_{sys}$ only apart by +0.5102 from the currently most accepted value of $d_{LMC}$ = $49.97$ Kpc (Pietrzyński., et al, 2014)., in this paper, the value of $d_{LMC}$ was obtained by combining the distances determined from the RR Lyrae and classical cepheids variable stars and the supernova SN1987a.
