Preliminary evidence is presented which indicates that the star WX Cen, associated with the X-ray source Centaurus X-2 belongs to the Scorpio-Centaurus association. It is pointed out that this result greatly strengthens the similar results for the source Scorpius X-1, and lends support to the idea of the existence of a class of X-ray stars formed by young, subluminous objects, probably supernova remnants, thus neutron stars.
