Population number syntesis and chemical evolution of galaxies, with a realistic binary frequency.

Project Details


Astrophysics tries to understand the physiscs behind the structure and evolution of all stars: in the entire mass-range, single stars and binaries. The model of our sun lead us to a understand the structure of its atmosphere and the necessity of nuclear fusion in its interior.The study of single stars can nowe refer to a long tradition of thories which are confirmed by observations: White Dwarfs, Wolf Rayet Stars, Super Novae, Neutron Stars, Black Holes, ... Still many observed stellar features remain unexplained by single star evolution and need to be explained by the evolution of interacting binaries. Large telescopes yield observations of large groups of stars (e.g. galaxies) so that observations of the combined spectra of a large number of stars can now be interpreted in terms of single star and binary evolution. The individual components of interacting binaries evolve completely different than single stars. Using its tradition and expertise on binary research, the 'Astrophysical Institute' of the VUB formulates a project that aims to explain as many as possible obvious stellar characteristics by a scenario in which in a large group of stars the single stars evolve as single stars, but the components of a binary do NOT evolve as two independant binaries.
