2507 20160701171706.0 ASTROimport-664 Frémat, Y. 2004 Spectroscopic disentangling of the triple system DG Leo DG Leo is a partly unresolved triple system composed of 3 very similar stars (A8 V), of which one at least is a δ Scuti star. The composite nature of the spectrum inhibits a careful analysis of the pulsation. The spectrum disentangling method as introduced by Hadrava (1995) is therefore applied to derive radial velocities at all orbital phases and to separate the spectrum of each component. Stellar fundamental parameters are then estimated from these individual spectra applying a classical model atmosphere analysis. From this study, it turns out that both components of the close binary are mild-Am stars, while the chemically ``normal" third component is pulsating. Lampens, P. Hensberge, H.
