The Heckmann's wormholes in Jordan-Brans-Dicke gravity

A simple Heckmann’s vacuum wormhole solution of Jordan-Brans-Dicke gravitation is presented and analysed. It is shown that in contrast with class I Brans solution where the throat radius becomes real when $\omega <-4\mathrm{/}3$ here it becomes positive when $\omega <-1$.
