The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

There is now strong evidence for stars that have been born with initial helium mass fractions as high as Y=0.40, such as in the globular cluster Omega Centauri. However, the evolution, chemical yields, and final fates of helium-rich stars are poorly understood. In this talk, I will present results for the evolution and nucleosynthesis of asymptotic giant branch models with masses of 3 to 6 Msun at a metallicity of [Fe/H] ~= -1.4 with He-normal and He-rich compositions. ...
