Structure of Stationary Photodissociation Fronts
The structure of stationary photodissociation fronts is revisited. H 2 self-shielding is discussed, including the eeects of line overlap. We nd that line overlap is important for N(H 2) > 10 20 cm ?2 , with a factor-of-two suppression of pumping rates at column densities N(H 2) 3 10 20 cm ?2. We compute multiline UV pumping models, and compare these with simple analytic approximations for the e...

The structure of stationary photodissociation fronts is revisited. H2 self-shielding is discussed, including the effects of line overlap. We find that line overlap is important for N(H2) ∼> 1020 cm−2, with a factor-of-two suppression of pumping rates at column densities N(H2) ≈ 3 × 1020 cm−2. We compute multiline UV pumping models, and compare these with simple analytic approximations for the e...
متن کاملAsymmetric counterpropagating fronts without flow.
Out-of-equilibrium systems exhibit domain walls between different states. These walls, depending on the type of connected states, can display rich spatiotemporal dynamics. In this Rapid Communication, we investigate the asymmetrical counterpropagation of fronts in an in-plane-switching cell filled with a nematic liquid crystal. Experimentally, we characterize the different front shapes and prop...
متن کاملThe Abundance of Atomic Carbon near the Ionization Fronts
We have observed the 492 GHz ground-state line of atomic carbon in the edge-on ionization fronts in M17 and .s1~0. y.te find that, contrary to expectation, the C I emission peaks farther into the molecular cloud from t~e Iomza~IO~ fro~t than does the CO. In fact the peak C I abundance in M17 occurs more than 60 mag of visual extmctton mto the cloud from the ionization front. Calculations of the...
متن کاملA near-stationary subspace for ridge approximation
Response surfaces are common surrogates for expensive computer simulations in engineering analysis. However, the cost of fitting an accurate response surface increases exponentially as the number of model inputs increases, which leaves response surface construction intractable for many models. We propose ridge approximation for fitting response surfaces in several variables. A ridge function is...
