dc.description.abstractSe diseñaron programas en Matlab, que aplican el método de fotometría de apertura diferencial, a dos imágenes tomadas con un dispositivo de carga acoplada (CCD) en los filtros visible V y azul B, para calcular los parámetros físicos (el flujo ( f ), la magnitud aparente (mV ) y con la corrección al enrojecimiento (V0 ), el índice de color (B −V ) y (B −V )0 , el logaritmo de la temperatura efectiva (logTeff ), la magnitud absoluta (MV ), la magnitud bolométrica (M B ) y el log (L∗/L?? )) de cada estrella estudiada perteneciente al cúmulo abierto NGC 6611.Una vez obtenidos los parámetros, se graficó el diagrama de color-magnitud y por el método de ajuste de la secuencia principal se encontró el módulo de la distancia y la distancia del cúmulo, suponiendo que todas las estrellas se encuentran a la misma distancia y que aproximadamente nacieron en el mismo instante.en_US
dc.description.abstractMatlab programs were designed to apply differential aperture photometry. Two images were taken with a charge-couple device (CCD) in the visible V and blue filters, to calculate physical parameters (the flux( f ), the apparent magnitude (mV ) and its reddening corrected value(V0 ), color index (B −V ) and (B −V )0 , the log of effective temperature (logTeff ), the absolute magnitude (MV ), the bolometric magnitude (MB ) & log(L∗ L?? )) of each studied star pertaining to the open cluster NGC 6611.Upon obtaining the parameters, the color-magnitude diagram was graphed and by fitting to the main sequence, the distance modulus and thus the distance to the cluster was found. The stars were assumed to be at the same distance and born at approximately the same moment.en_US
