Abstract

We report results on the spectroscopic follow-up of Nova SMC 2001 and Nova LMC 2002 carried out at La Silla. The analysis of the spectroscopic evolution shows that these objects belong to the {\sl Fe II} class, according to the Cerro Tololo scheme. From the line fluxes and the expansion velocities, we have derived an approximate mass for the ejected shells of 2 $\div 3 \times 1 0^{- 4} M_{⊙}$ . The filling factor measurements ( $ε \sim 1 0^{- 4} \div 1 0^{- 1}$ ) suggest a clumpy structure for the ejecta.
