Abstract
The physical state of ionized gas in NGC 7793 was studied by spectroscopical means: the electronic temperature isT e∼104K while the electronic density ranges fromN e∼1400 cm−3 in the nucleus toN e∼1000 cm−3 in the emission regions. There are also indications of an excess of nitrogen in the nucleus. TheM/L ratio suggests for NGC 7793, a high proportion of young objects quite uniformly distributed over its body, with a slight concentration towards the nuclear region.
