In this work we present a sample of elliptical interacting galaxy pairs connected by a bridge, obtained from a visual classification of a pair catalogue dereived from the data of the 7th Sloan Digital Sky Survey (SDSS-DR7). We present preliminary results of the general characteristics of galaxies in these systems, such as star formation rate, age of the stellar populations, concentration indices, colours and environment local density.www.iafe.uba.ar/AstroNum/html/workshop2014publishedVersionAstronomía (incluye Astrofísica y Ciencias del Espacio
