Chemical abundances in 7 metal-poor HII regions and a determination of the primordial helium abundance

Mabel Valerdi, Antonio Peimbert, Manuel Peimbert

We conducted a long-slit spectrophotometry analysis to obtain the chemical abundances of seven metal-poor HII regions in three galaxies: UM 160, UM 420, and TOL 0513-393. The data…
