Helium abundance determination in hii regions of blue compact dwarf galaxies
We present detail study of helium ionic abundances of HII regions in Blue Compact Dwarf galaxies using new emissivities from [3]. On the base of new helium He/H and heavy elements abundances A/H [1, 2] different types of Y–Z dependences were analyzed. The values of primordial helium abundance Yp and...
