The Importance of Nonlinear H2 Photoexcitiation in Strongly Irradiated PDRs

P. P. Sorokin, J. H. Glownia, R. T. Hodgson

It is shown that, under sufficiently intense OB-star illumination of a stationary photoexcitation front (PDR), nonlinear H2 photoexcitation processes comprising driven resonant two…
