Deviations from He I Case B Recombination Theory and Extinction Corrections in the Orion Nebula
K. P. M. Blagrave, P. G. Martin, R. H. Rubin +4
We are engaged in a comprehensive program to find reliable elemental abundances in and to probe the physical structure of the Orion Nebula, the brightest and best-resolved H II reg…
A photoionized Herbig-Haro object in the Orion nebula
K. P. M. Blagrave, P. G. Martin, J. A. Baldwin
The spectra of Herbig Haro objects are usually characteristic of ionization and excitation in shock-heated gas, whether an internal shock in an unsteady outflow or a bow shock inte…
On the O II ground configuration energy levels
K. P. M. Blagrave, P. G. Martin
The most accurate way to measure the energy levels for the O II 2p^3 ground configuration has been from the forbidden lines in planetary nebulae. We present an analysis of modern p…
Temperature Variations from HST Spectroscopy of the Orion Nebula
R. H. Rubin, P. G. Martin, R. J. Dufour +5
We present HST/STIS long-slit spectroscopy of NGC 1976. Our goal is to measure the intrinsic line ratio [O III] 4364/5008 and thereby evaluate the electron temperature (T_e) and th…
