Scientific paper

Recently, several hybrid objects have been found with the far-IR and OH maser emission characteristics of the highly evolved red giant stars known as OH-IR sources, but also with radio continuum emission from a central H II region. Here, radio-interferometer maps are presented of OH maser emission at 1612 MHz from the OH-IR sources Vy2-2 and OH0.9 + 1.3. The maps reveal shell structure in the masers, which is taken to be conclusive evidence of an evolutionary link between OH-IR sources and PN.
