Scientific paper

LIADA's (Iberoamerica League of Astronomy) Double Star Section studied 103 neglected visual double stars during 2003. BVIJHK photometries, astrometric and kinematical data were used/obtained to determine their nature using several criteria and classifying them as optical, physical or common origin pairs. Only 12 % were physical double stars or common origin pairs, i.e. binaries. Their angular separations range from 4.01" to 47.89". In this work I comment in detail on these binaries and determine their expected semimajor axis and orbital period.
