A number of objects which may be proto-planetary nebulae are being studied. They were found through a radio search of early-type emission-line stars, and the radio emission is believed to originate in extensive circumstellar ionised gas. The objects have an infrared spectrum which indicates the presence of dust, and a continuum radio spectrum characteristic of prolonged mass outflow from the central star. Of the five objects discussed here, Vy2-2, Hbl2, HD167362, Hl-36 and V1016 Cygni, a distance is available for only the last: for that object the calculated mass of the ionized gas is 0.02 M0 (see Ahem et al, 1977). If this is typical of the five, then they may represent the early stages of the low-mass planetary nebulae discussed by Wood and Cahn (1977).
