RESUMEN

A partir de fotometría fotoeléctrica uvby – β del cúmulo abierto NGC 2343 (20 estrellas) realizamos la determinación de distancias de cada una y, por ende, la pertenencia de las estrellas al cúmulo. Asimismo se determinaron el enrojecimiento y la edad.

 

ABSTRACT

From uvby − β photometry of the open cluster NGC 2343 (20 stars) we were able to determine membership of the stars to the cluster and fix its age and reddening.

Key Words: open clusters and associations: individual (NGC2343) —techniques: photometric.
