Spectroscopy of Outlying H II Regions in Spiral Galaxies: Abundances and Radial Gradients
L. van Zee, J. J. Salzer, M. P. Haynes +2
We present the results of low dispersion optical spectroscopy of 186 H II regions spanning a range of radius in 13 spiral galaxies. Abundances for several elements (oxygen, nitroge…
Neutral Gas Distributions and Kinematics of Five Blue Compact Dwarf Galaxies
L. van Zee, E. D. Skillman, J. J. Salzer
We present the results of high spatial resolution HI observations of five intrinsically compact dwarf galaxies which are currently experiencing a strong burst of star formation. Th…
Abundances in Spiral Galaxies: Evidence for Primary Nitrogen Production
L. van Zee, J. J. Salzer, M. P. Haynes
We present the results of nitrogen and oxygen abundance measurements for 185 HII regions spanning a range of radius in 13 spiral galaxies. As expected, the nitrogen-to-oxygen ratio…
