How does Fowler's work relate to exoplanet habitability?
My work on stellar nucleosynthesis directly informs exoplanet habitability because the raw materials for rocky planets and life—carbon, oxygen, nitrogen, iron—are produced in stars. The relative abundances of these elements depend on the nuclear reaction rates I measured, like the triple-alpha process and the 12C(α,γ)16O reaction. A star's composition determines the types of planets that can form around it. For example, a star with a high carbon-to-oxygen ratio might produce carbon-rich planets, while a solar-like ratio yields silicate-rich worlds. Also, the s-process and r-process supply elements like phosphorus and potassium, essential for biochemistry. When astronomers search for habitable exoplanets, they rely on stellar models that incorporate my cross-section data. The evidence is clear: we are stardust, and that same stardust seeds planetary systems. Understanding nucleosynthesis is key to knowing where life might arise.
