The physics of photodissociation regions
Astrophysics and Space Science, 2010Photodissociation Regions (PDRs) are gas phases in which ultraviolet radiation plays a role in the heating or chemistry. The physics of PDRs determines the emitted radiation and physical conditions in both the diffuse atomic interstellar medium and the dense molecular phases. High energy laboratory experiments can provide constraints on the survival of

Anatomy of the Photodissociation Region in the Orion Bar
Science, 1993Much of the interstellar gas resides in photodissociation regions whose chemistry and energy balance is controlled by the flux of far-ultraviolet radiation upon them. These photons can ionize and dissociate molecules and heat the gas through the photoelectric effect working on dust grains.
