Abstract (from CDS):

We have used the radial velocity variations of two sdB stars previously reported to be binaries to establish their orbital periods. They are PG0940+068 (P=8.33d) and PG1247+554 (P=0.599d). The minimum masses of the unseen companions, assuming a mass of 0.5M☉ for the sdB stars, are 0.090±0.003M. for PG1247+554 and 0.63±0.02M☉ for PG0940+068. The nature of the companions is not constrained further by our data.
