CONCLUSIONS<br />
Us<strong>in</strong>g NH3360 we have separated the C & N contributions<br />
C overabundance <strong>in</strong> massive <strong>Elliptical</strong>s<br />
Correlates with σ<br />
Differences with environment<br />
Formation of field E from a previously C-enriched gas.<br />
Coma E were fully assembled before the massive release of C<br />
A richer star formation history <strong>in</strong> field E compared to Coma.<br />
N is mildly enhanced (with respect to solar ratio)<br />
NH3360 does NOT correlate with σ (PRIMARY)<br />
No differences with environment<br />
N is produced by massive <strong>and</strong> <strong>in</strong>termediate-mass stars (enrichment delay w.r.t. to Mg)<br />
C is likely produced <strong>in</strong> massive stars <strong>and</strong> lower mass stars<br />
Field galaxies have experienced a more extended SF history<br />
