Abstract (from CDS):

N 11, the second largest nebula of the LMC, is formed of a large bubble surrounded by 9 bright nebulae and filaments. We have observed this nebular complex with a scanning Fabry-Perot interferometer at Hα and [OIII] 5007 wavelengths. The kinematics of this field agrees with the results of the stellar content and of the molecular studies, and shows that such a structure can be the consequence of a sequential star formation. The elements of this result are deduced from the energetic input inside the ionized gas by the stellar winds of the associations LH9 and LH10. The evaluated dynamical lifespan of small nebular entities associated with the more massive stars of LH10, are found significantly shorter than for the gas ionized by the association LH9. Therefore sequential star formation can be triggered at the shock boundaries of the nebula excited by an OB association in a time scale shorter than previously found, and of at most a few 106yrs. It thus leads to the evidence for a new class of giant bubble, designated as "ring of HII regions" bubble with several distinctive characteristics. It is discussed that the bubbles of this type are formed by sequential star formation over time scales shorter than previously found for some superbubbles.
