         Lecture Course "Solar Spectrum Formation"

Goal: become optically thick for studying the chromosphere 

Content
  line and continuum particle-photon processes
  radiative transfer
  thin cloud > LTE > NLTE > PRD > non-E 
  NB: no polarimetry

Daily schedule         # Friday's 10:00-12:00, 13:00-15:00 was better
  13:00-14:00 theory
    14:00-14:20 coffee
  14:20-15:15 theory
    15:15-15:45 break
  15:45-16:30 examples

Tuesday Nov 29 
  dawn of astrophysics 
  exercises, literature
  basic solar spectrum formation (SSI)
    continuum
      observed intensity > depth of viewing > Hmin extinction
    lines
      bb processes
      bb process pairs: collisional or scattering addition or reduction
      photospheric line = map extinction and source function via depth
  basic RT quantities
    intensity, conservation (exam in break)
    emissivity, extinction, source function
      S as weighted process combination
      [S,alpha] more orthogonal than [j,alpha]
      stimulated emission = negative extinction 
    transport equation
    constant-S cloud
  examples
    cloud modeling
    ALMA lines?
    white-light corona = Thomson scattering with Fraunhofer line erasure
    forbidden optical lines = very high ionization stages
    EUV coronal line formation = coronal equilibrium = thermal photons
    EUV dark = bound-free scattering HI, HeI, HeII edges out of passband
