The Region of Triggered Star Formation W40: Observations and Model
arXiv:1503.08010 · doi:10.1134/S1063772915050078
Abstract
A "collect and collapse" model of triggered star formation is used to estimate the parameters of ring-like structure consisted of a sequence of low-mass clumps in the W40 region. The model parameters are close to the observed ones if the density of the cloud in which the HII zone is expanding is fairly high (>~ 10^5 cm^{-3}) and the luminosity of the driving source exceeds previous estimate. Probable reasons for the scatter of the observed parameters of the clumps are discussed.
