Abstract We use trees to construct families of algebraic integers. These include certain families of Salem numbers and of Pisot numbers, constructed from stars. The family of Pisot numbers we construct forms a proper closed subset of the set of all Pisot numbers. We show that this subset contains Pisot numbers of arbitrary trace. In particular, we exhibit a Pisot number of trace -- 5 and degree 141, 731, 565, 070, 951.
