Abstract: The recent discovery of a giant planet orbiting the subdwarf B (sdB) pulsator V391 Pegasi has interesting implications not only for the late stage evolution of planetary systems, but also for the various scenarios that have been proposed for the formation of sdB stars and, more in general, for the irregular morphologies of the horizontal branches in globular clusters and elliptical galaxies. In this paper we describe a few of these scenarios and discuss some implications.
