Research ArticleOpen accessPhrase in the titleGravity Assist and Scattering off AGB Stars off Molecular CloudsAhmad Hashem AbdelhadiThe scattering of stellar orbits by galactic molecular clouds is studied in hope of explaining isotopic peculiarities of presolar grains from Asymptotic Giant Branch (AGB) stars. Silicon isotopic anomalies found in the mainstream Silicon Carbide (SiC) grains are observed to have heavy isotopes enriched. To explain the isotopic heaviness I propose that AGB stars that formed in the interior region … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,420 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAsymptotic Giant Branch Stars Migration from the Central of the Milky Way Galaxy to our Sun’s Birthplace and its Relation with Silicon Carbide GrainsAhmad Hashem AbdelhadiSilicon carbide grains found in meteorites are peculiar in their age and isotopic ratios; they formed before the Sun was born and their isotopic signature indicates that they come from a different galactic region. This study aims to seek a possible paradigm for such richness and peculiarity through Monte Carlo simulation of scattering of Asymptotic Giant Branch (AGB) stars off … …Space Science International, Vol. 1, Issue 1 · 20 Jun 2013 · 7,053 accessesView PDF Cite
