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. |
