dc.description.abstractEn este trabajo se determinó la distancia y el exceso de color interno de las galaxias NGC 6822, NGC 7793, WLM, NGC 3109 y NGC 300 mediante la Ley de Leavitt (LL) en filtros VIJK. La relación lineal en un filtro dado de la magnitud aparente y el logaritmo del periodo, de las variables Cefeidas de una galaxia, de la que se deriva la LL, se considera universal en el sentido de que la pendiente de la relación es la misma para todas las galaxias. La galaxia a partir de la cual se calcula la pendiente de la LL es la Gran Nube de Magallanes (LMC), con una metalicidad de -0.5 dex. En este trabajo utilizamos los resultados de LL para la LMC de Udalski (2000) para VI y Persson et al. (2004) para JK. Para verificar la universalidad de LL, los cálculos de distancia y exceso de color se realizaron sin asumir universalidad, es decir, trabajamos con una pendiente libre. Además, se restó la extinción del medio intergaláctico de los conjuntos de datos de cada galaxia para estudiar el exceso de color interno de la galaxia. Las galaxias estudiadas tienen metalicidades en el rango de -0.5 a -1.86 dex, para estudiar si hay cambios de los resultados de LL en función de la metalicidad. La LL se calculó utilizando una regresión MM robusta, que trata adecuadamente los valores atípicos y los datos extremos. La comparación de los resultados obtenidos con los reportados en el proyecto Araucaria y la base de datos NED/IPAC llevó a tres conclusiones. En primer lugar, las pendientes de todas las galaxias difieren de la LMC, sin embargo, no se observaron diferencias de las pendientes con respecto a la LMC en función de la metalicidad. En segundo lugar, los excesos de color obtenidos muestran una gran discrepancia con los valores reportados en la literatura. Finalmente, con el análisis de las pendientes para los filtros VIJK de la LL, el módulo de distancia verdadero, la distancia y el exceso de color de las cinco galaxias estudiadas no fue posible concluir sobre la universalidad de la LL, además, tampoco se identificó cómo cambia la LL con la metalicidad.
