Determination of the primordial helium abundance based on NGC 346 an HII region of the Small Magellanic Cloud
Mabel Valerdi, Antonio Peimbert, Manuel Peimbert +1
To place meaningful constraints on Big Bang Nucleosynthesis models, the primordial helium abundance determination is crucial. Low-metallicity HII regions have been used to estimate…
