; Cosmic Elements
: '''Stellar Nucleosynthesis''' → The process of creating elements (Oxygen, Silicon, etc.) inside stars.
: '''Alpha Process''' → Creating elements by adding Helium nuclei (Alpha particles).
: '''R-Process''' → The rapid neutron capture during a Supernova that creates heavy elements like Gold and Uranium.
: '''Binary Systems''' → Most stars come in pairs; they can "steal" mass from each other, changing their evolutionary path.
