Abstract

A revised orbit for the visual binary A 2329, calculated taking into account a set of interferometric measures distributed over one orbital revolution, is presented. On the basis of new orbital elements and the Hipparcos parallax, a dynamical mass of the system of 1.25+/-0.14 M_⊙ is obtained. By considering new spectral data, we confirm its MK spectral type as K7V.
