IUE spectroscopy of extragalactic H II regions
Technical Report
·
OSTI ID:5472616
The UV spectra of several prominent extragalactic H II regions were studied with the IUE during the two years. High dispersion spectra were obtained of N81 and N66A in the SMC, the 30 Doradus Nebula in the LMC, NGC 2363 in the SBm galaxy NGC 2366, NGC 5471 in M101, and NGC 604 in M33, that are superior in quality to low dispersion spectra in the statistical accuracy and resolution of the nebular emission lines of ions such as C III, Si III, N III, and O III. These data are combined with ground based spectroscopy to diagnose physical conditions (temperatures, densities, and ionization) and abundances in over twenty extragalactic H II regions derived from recent IUE low dispersion observations and/or archival spectra are also presented.
