Chemical Abundances in our Galaxy and Other Galaxies Derived from H II Regions
M. Peimbert, L. Carigi, A. Peimbert
We discuss the accuracy of the abundance determinations of H II regions in our Galaxy and other galaxies. We focus on the main observational constraints derived from abundance dete…

The Chemical Composition of the Small Magellanic Cloud H II Region NGC 346 and the Primordial Helium Abundance
Manuel Peimbert, Antonio Peimbert, Maria Teresa Ruiz
Spectrophotometry in the 3400-7400 range is presented for 13 areas of the brightest H II region in the SMC: NGC 346. The observations were obtained at CTIO with the 4-m telescope.…

The Magellanic Clouds and the Primordial Helium Abundance
Manuel Peimbert Antonio Peimbert
A new determination of the pregalactic helium abundance based on the Magellanic Clouds H II regions is discussed. This determination amounts to Yp = 0.2345 +- 0.0030 and is compare…
