Study of Photon Dominated Regions in Cepheus B
Aims. The aim of the paper is to understand the emission from the photon dominated regions in Cepheus B, estimate the column densities of neutral carbon in bulk of the gas in Cepheus B and to derive constraints on the factors which determine the abundance of neutral carbon relative to CO. Methods. This paper presents 15×15 fully sampled maps of [C ] at 492 GHz and 12CO 4–3 observed with KOSMA ...
متن کاملCarbon budget and carbon chemistry in Photon Dominated Regions
We present a study of small carbon chains and rings in Photon Dominated Regions (PDRs) performed at millimetre wavelengths. Our sample consists of the Horsehead nebula (B33), the ρ Oph L1688 cloud interface, and the cometary-shaped cloud IC63. Using the IRAM 30-m telescope, the SEST and the Effelsberg 100-m telescope at Effelsberg., we mapped the emission of C2H, c-C3H2 and C4H, and searched fo...
متن کاملPhoton Dominated Regions in Low Uv Fields: a Study of the Peripheral Region of L1204/s140
We have carried out an in-depth study of the peripheral region of the molecular cloud L1204/S140, where the far-ultraviolet radiation and the density are relatively low. Our observations test theories of photon-dominated regions (PDRs) in a regime that has been little explored. Knowledge of such regions will also help to test theories of photoionization-regulated star formation. [C II] 158 μm a...
متن کاملSome empirical estimates of the H2 formation rate in photon-dominated regions
We combine recent ISO observations of the vibrational ground state lines of H2 towards PhotonDominated Regions (PDRs) with observations of vibrationally excited states made with ground-based telescopes in order to constrain the formation rate of H2 on grain surfaces under the physical conditions in the layers responsible for H2 emission. We use steady state PDR models in order to examine the se...
متن کاملPhysical models of photon - dominated regions : influence of clumpiness and geometry for S 140
Model calculations for the photon-dominated region S 140 are presented. The overall geometry and an inhomogeneous density distribution are incorporated and the chemical and thermal balance is solved in two and three dimensions. The observed widespread neutral carbon emission in the extended molecular cloud is investigated for a range in clump size and volume filling factor. It is found that the...
