Modelisations of galactic 1.275 MeV emission produced by the decay 22 Na have been performed for several frequency-spatial distributions of ONe novae. Recent results of nova rates and their distributions in our Galaxy have been used. These modelisations allow to estimate the lower-limit of the 22 Na mass ejected per ONe novae detectable with the future spectrometer (SPI) of the INTEGRAL observa...

We suggest new evolutionary scenarios for non-magnetic short orbital period CVs. The first model is the analogy of the 'hibernation scenario' or the 'modern hibernation scenario'. The second one is an extension of Mukai & Naylor (1995) ideas. All models imply a tight connection between permanent superhump systems and classical novae. We highlight the significance of the observed evolution of V1...

The spectrometer SPI on board INTEGRAL is capable of high-resolution spectroscopic studies in the energy range 20 keV to 8 MeV for GRBs which occur within the fully coded field of view (16 • corner to corner). Six GRBs occurred within the SPI field of view between October 2002 and November 2003. We present results of the analysis of the first two GRBs detected by SPI after the payload performan...

In this talk, I describe a calculation of the geodesics since last scattering and derive the dependence of the position of the first Doppler Peak on Ωm and ΩΛ.
