Herschel imaging of the dust in the Helix Nebula (NGC 7293)
G. C. Van de Steene, P. A. M. van Hoof, K. M. Exter +19
In our series of papers presenting the Herschel imaging of evolved planetary nebulae, we present images of the dust distribution in the Helix nebula (NGC 7293). Images at 70, 160,…
Herschel Far-Infrared Spectral-mapping of Orion BN/KL Outflows: Spatial distribution of excited CO, H2O, OH, O and C+ in shocked gas
Javier R. Goicoechea, Luis Chavarria, Jose Cernicharo +8
We present ~2'x2' spectral-maps of Orion BN/KL outflows taken with Herschel at ~12'' resolution. For the first time in the far-IR domain, we spatially resolve the emission associat…
The JCMT Legacy Survey of the Gould Belt: a molecular line study of the Ophiuchus molecular cloud
Glenn J. White, Emily Drabek-Maunder, Erik Rosolowsky +17
CO, CO and CO = 3--2 observations are presented of the Ophiuchus molecular cloud. The CO and CO emission is dominated by the Oph A clump, and…
OH+ in astrophysical media: state-to-state formation rates, Einstein coefficients and inelastic collision rates with He
S. Gomez-Carrasco, B. Godard, F. Lique +9
The rate constants required to model the OH observations in different regions of the interstellar medium have been determined using state of the art quantum methods. First, sta…
Herschel spectral-mapping of the Helix Nebula (NGC 7293): Extended CO photodissociation and OH+ emission
M. Etxaluze, J. Cernicharo, J. R. Goicoechea +13
The Helix Nebula (NGC 7293) is the closest planetary nebulae. Therefore, it is an ideal template for photochemical studies at small spatial scales in planetary nebulae. We aim to s…
