Compression Disturbances in the Atomic Zone of Photodissociation Regions of Interstellar Gas
The parameters of autowave compression pulses formed in isentropically unstable atomic regions of the Orion Bar are estimated. The dependences of the density, pressure, and velocity amplitudes on the equilibrium temperature are determined. The obtained values are compared with observed nonthermal tu...

Summary: | The parameters of autowave compression pulses formed in isentropically unstable atomic regions of the Orion Bar are estimated. The dependences of the density, pressure, and velocity amplitudes on the equilibrium temperature are determined. The obtained values are compared with observed nonthermal turbulent velocity pulsations and pressure disturbances. |
