The three dimensional dynamic structure of the inner Orion Nebula
C. R. O'Dell, W. J. Henney, N. P. Abel +2
The three dimensional structure of the brightest part of the Orion Nebula is assessed in the light of published and new data. We find that the widely accepted model of a concave bl…
Radiation-magnetohydrodynamic simulations of the photoionisation of magnetised globules
William J. Henney, S. Jane Arthur, Fabio De Colle +1
We present the first three-dimensional radiation-magnetohydrodynamic simulations of the photoionisation of a dense, magnetised molecular globule by an external source of ultraviole…
High Velocity Features in the Orion Nebula
C. R. O'Dell, W. J. Henney
We have used widely spaced in time Hubble Space Telescope images to determine tangential velocities of features associated with outflows from young stars. These observations were s…
Merged ionization/dissociation fronts in planetary nebulae
William J. Henney, R. J. R. Williams, Gary J. Ferland +2
The hydrogen ionization and dissociation front around an ultraviolet radiation source should merge when the ratio of ionizing photon flux to gas density is sufficiently low and the…
Oxygen-rich droplets and the enrichment of the ISM
G. Stasinska, G. Tenorio-Tagle, M. Rodriguez +1
We argue that the discrepancies observed in HII regions between abundances derived from optical recombination lines (ORLs) and collisionally excited lines (CELs) might well be the…
Large Scale Flows from Orion-South
W. J. Henney, C. R. O'Dell, Luis A. Zapata +3
Multiple optical outflows are known to exist in the vicinity of the active star formation region called Orion-South (Orion-S). We have mapped the velocity of low ionization feature…
