Excitation of emission lines by fluorescence and recombination in IC418
V. Escalante, C. Morisset, L. Georgiev
We compare calculated intensities of lines of CII, NI, NII, OI and OII with a published deep spectroscopic survey of planetary nebula IC 418. Our calculations use a self-consistent…
Excitation of emission lines by fluorescence and recombination in IC 418
V. Escalante, C. Morisset, L. Georgiev
We predict intensities of lines of CII, NI, NII, OI and OII and compare them with a deep spectroscopic survey of IC 418 to test the effect of excitation of nebular emission lines b…
An Expanding HI Photodissociated Region Associated with the Compact HII Region G213.880-11.837 in the GGD 14 Complex
Yolanda Gomez, Guido Garay, Carlos A. Rodriguez-Rico +5
We present high angular and spectral resolution HI 21~cm line observations toward the cometary-shaped compact HII region G213.880-11.837 in the GGD~14 complex.The kinematics and mo…
A Comparison between Anomalous 6-cm HCO Absorption and CO(1-0) Emission in the L1204/S140
Monica Ivette Rodriguez, Tommy Wiklind, Ronald J. Allen +2
We report observations of the dust cloud L1204 with the Onsala 25-m telescope in the 6 cm (1) transition of \htco. The observed region includes the S140 H arc. Thi…
The NII spectrum of the Orion Nebula
Vladimir Escalante, Christophe Morisset
The predicted emission spectrum of NII is compared with observations of permitted lines in the Orion nebula. Conventional nebular models show that the intensities of the more inten…
