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÷3×104M\div3\times 10^{-4} M_\odot. The filling factor measurements (ϵ104÷101\epsilon\sim 10^{-4}\div 10^{-1}) suggest a clumpy structure for the ejecta.
