Beyond the [OIII]$\hat{I}»$4363 auroral line: [NeIII]$\hat{I}»$3868 as a direct tracer of electron temperature

Borja Pérez-Díaz, José M. Vílchez, Marco Castellano +9

Auroral lines enable accurate measurements of chemical abundances in ionized gaseous nebulae thanks to their sensitivity to electron temperature. However, metal-enriched systems re…
