Scientific paper

Microwave CO and (C-13)O observations of the elephant-trunk globules in the northwest quadrant of the Rosette nebula (NGC 2237-2246) are discussed in light of recent work on stellar winds. An age for the globules and the nebula is derived and their masses and evaporation lifetimes are estimated. It is suggested that the formation of the elephant trunk globules is the result of stellar-wind action in the H II region. Models of globule formation are considered and a mechanism based on the Rayleigh-Taylor instability is evaluated.
