Spitzer observations of extragalactic H II regions - III. NGC 6822 and the hot star, H II region connection
Robert H. Rubin, Janet P. Simpson, Sean W. J. Colgan +5
Using the short-high module of the Infrared Spectrograph on the Spitzer Space Telescope, we have measured the [S IV] 10.51, [Ne II] 12.81, [Ne III] 15.56, and [S III] 18.71-micron…
The Nature and Frequency of Outflows from Stars in the Central Orion Nebula Cluster
C. R. O'Dell, G. J. Ferland, W. J. Henney +3
Recent Hubble Space Telescope images have allowed the determination with unprecedented accuracy of motions and changes of shocks within the inner Orion Nebula. These originate from…
Spitzer reveals what's behind Orion's Bar
Robert H. Rubin, Janet P. Simpson, C. R. O'Dell +5
We present Spitzer Space Telescope observations of 11 regions SE of the Bright Bar in the Orion Nebula, along a radial from the exciting star theta1OriC, extending from 2.6 to 12.1…
Multiconfiguration Dirac-Hartree-Fock energy levels and transition probabilities for 3d^5 in Fe IV
C. Froese Fischer, R. H. Rubin, M. Rodríguez
Multiconfiguration Dirac-Hartree-Fock electric quadrupole (E2) and magnetic dipole (M1) transition probabilities are reported for transitions between levels of 3d^5 in [Fe IV]. The…
Spitzer Observations of M33 and the Hot Star, H II Region Connection
Robert H. Rubin, Janet P. Simpson, Sean W. J. Colgan +7
We have observed emission lines of [S IV] 10.51, H(7-6) 12.37, [Ne II] 12.81, [Ne III] 15.56, and [S III] 18.71 um in a number of extragalactic H II regions with the Spitzer Space…
Spitzer IRS Observations of the Galactic Center: Shocked Gas in the Radio Arc Bubble
Janet P. Simpson, Sean W. J. Colgan, Angela S. Cotera +4
We present Spitzer IRS spectra (R ~600, 10 - 38 micron) of 38 positions in the Galactic Center (GC), all at the same Galactic longitude and spanning plus/minus 0.3 degrees in latit…
