On the electron temperature determination in high-metallicity H ii regions

The problem of determination of the electron temperature t 2 in the O+ zone of high-metallicity H ii regions is examined. It is shown that the ratio of nebular to auroral nitrogen line intensities, which is an indicator of the electron temperature t 2, can be expressed in terms of the nebular line i...
