Light and Atoms: the Quantum Microworld

"Ordinary" Matter

• atoms
• hydrogen atom emission and absorption spectrum
• hydrogen atom simulation
• composition the periodic table

Spectroscopy & Kirchhoff's Rules

• solar spectrum
• interstellar gas in spectra of nearby white dwarf stars

Dark Matter Candidate: Cold Gas

• cold gas as dark matter
• testing for cold gas: absorption lines from atoms

Star Birth

• fuel for star formatin: gas and dust
• stellar nurserys: molecular clouds
  • all-sky (CO data)
  • Barnard 68 (optical and IR)
  • Orion, nebula: HST optical and zoom, IR
  • M16: Eagle nebula and HST zoom to pillars of creation
  • on other galaxies: M51/Whirlpool optical/IR, CO molecules

Gravitational Collapse

Atoms, Gasses, Temperature, and Pressure

• demos here, and here

Stars: Stability, Lifespan, and Energy Supply
