         Lecture Course "Solar Spectrum Formation"

Goal: become optically thick for studying the chromosphere wth IRIS

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

dialy schedule        
--------------
  10:00-10:50 theory
  11:00-11:50 theory
    lunch
  14:00-14:50 theory
  15:00-15:50 examples

#1 Friday May 4 
  dawn of astrophysics:  Cannon > Payne > HRD 
  latexania: my solar ADS collection, bibtex, \citeads
    Lockyer chromosphere 
  basic solar spectrum formation
    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
  examples
    white-light corona = Thomson scattering with Fraunhofer line erasure
    forbidden optical coronal 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

#2 Friday May 11
  review painting
  basic RT quantities
    intensity, conservation (exam in break)
    emissivity, extinction, source function
      S weighted processes
      [S,alpha] more orthogonal than [j,alpha]
      stimulated emission = negative extinction, not in scattering 
    transport equation
    constant-S cloud
  simple RT
    plane-parallel RT 
    Eddington-Barbier
  LTE plane-parallel spectrum formation 
    continua
      Gray, Vitense, solar optical 
    lines
      line broadening
      EB cartoons
  examples
    cloud modeling
    ultraviolet line flip
    Avrett solar spectrum cartoon
    start VALIIIC

#3 Friday May 18
  review painting
  lambda operator
  formal temperatures
  departure coefficients
  SE/non-E equations
  radiative heating/cooling
  RT with scattering 
    2-level source function
    sqrt(eps) law, thermalization depth
    Avrett 2-level results
  partial redistribution
  multi-level RT
  examples
    detour lines
    Mg 12-micron
  break = mugshots

#4 Tuesday May 29 (shifted from Friday May 25)
  review SE eqs
  PRD redistribution functions 
  VALIIIC continua, radiation budget
  hydrogen and Halpha in ALC7
  ALC7 line formation

#5a Thursday May 31 10:00-12:00 
  ALC7 Ly-alpha, Halpha, HeI, HeII
  ALC7 line formation compared to other standard models
  line pairs with ALC7 insights 
  standard-model comparisons
  examples
    Radyn shocks, Carlsson 4-panels

#5b Friday June 1 14:00-16:00
  Bifrost line synthesis
  IRIS diagnostics
  PSBE Halpha, EBs, non-E chromosphere, ALMA
