ANDRADE, M.. Orbit, masses and spectral analysis of the visual binary a 2329. Rev. mex. astron. astrofis [online]. 2007, vol.43, n.2, pp.237-242. ISSN 0185-1101.

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 is obtained. By considering new spectral data, we confirm its MK spectral type as K7V.
