Scattering

• coherent isotropic scattering
• awesome example: the blue sky
• awesome example: the solar corona (get excited for April 8, 2024)
• awesome example: reflection nebulae
  • Pleiades optical, IR
  • Blue Horsehead
  • Iris
• awesome example: light echo
  • variable star V838 Mon image, movie
  • light echo from SN 1987A
  • Circinus X-1
  • Cas A
  • random walks
  • scattering and absorption: albedo
  • stellar photospheres
    • themultiwavelength Sun today
    • Betelgeuse resolved: HST optical, IR, ALMA submm image, paper
    • circumstellar dus scattering in the Pleiades: relfection nebula
