LETGS: Carbon

Jeremy J. Drake (Smithsonian Astrophysical Observatory) Carbon. It’s everywhere these days. Popularized by the spewing chimneys of the industrial revolution, and explained by Fred Hoyle’s 12C resonance that facilitates Bethe’s triple-alpha process in stellar nucleosynthesis. They make everything with it … Continue reading
