This article presents a theoretical framework for the evolution of light element nuclides in the Galactic disc. The authors use two key assumptions: infall of metal-poor gas to the disc at an increasing rate, and destruction of fragile nuclides in hot relatively dense supergiant envelopes. Light nuclides are accelerated by supernova shocks, and

We present in this contribution the predictions on the multiwavelength spectral energy distribution of our evolutionary population synthesis models including single and binary stellar systems. The high energy computations include the emission associated to X-ray binaries and supernovae remnants, as well as the mechanical energy released into the

We present in this contribution our set of multiwavelength synthesis models including the evolution of single and binary stars. The main results we have obtained can be summarized as follows: (a) massive close-binary systems will start to experience mass transfer episodes after the first 4 Myr of the starburst evolution; (b) as a result of these
