The core theoretical lectures will be taught during the first week of the school and will cover two broad topics, "Instrumentation and Observations" and "Polarized Radiative Transfer" (~10 hours each). These lecture courses will be complemented by shorter lecture series (2-3 hours each, during the first and second week of the school) on adjacent topics. The detailed syllabus for the theoretical lectures will be posted in due course, here's just a synopsis:

Instrumentation and observations

This part will be taught by Bruce W. Lites (HAO/NCAR) and it will take ~10 hours.

  • Polarization of light (Jones & Mueller formalisms)
  • Modification of polarization by optical devices (polarizers & retarders)
  • Requirements for polarization measurements (noise, resolution...)
  • Approaches to polarimetry (modulation schemes, dual beam polarimetry...)
  • Spectral discriminators (spectrographs, filtergraphs, fiber optics...)
  • Modern polarimeters (examples)
  • Polarization calibration techniques

Polarized radiative transfer

Jose Carlos del Toro Iniesta (IAA, Spain) will be the lecturer for the theory of radiative transfer (~10 hours). Among other topics, we will see:

  • Absorption and dispersion
  • The radiative transfer equation (RTE): derivation, emission processes and spectral line formation
  • The RTE in the presence of a magnetic field (Zeeman effect, allowed transitions, elements of the propagation matrix, effective Zeeman triplet)
  • Solving the RTE (formal solution, symmetries, evolution operator, simple solutions, Milne-Eddington approximation)
  • Stokes spectrum diagnostics (tomography, contribution functions and response functions)

Additional lecture topics

There will also be shorter lecture courses (2-3 hours) on complementary topics:

  • Spectral line inversion algorithms by Rebecca Centeno (HAO, Boulder)
  • Non-LTE polarized radiative transfer by Han Uitenbroek (NSO, Boulder)
  • Magnetic field disambiguation techniques by KD Leka (NwRA, Boulder)
  • Scattering polarization and the Hanle effect by Roberto Casini (HAO/NCAR)

and some complementary activities:

  • Polarization lab by Alfred de Wijn (HAO/NCAR)
  • Simple diagnostics lab by Rebecca Centeno (HAO/NCAR)
  • Career development seminars (ASP/NCAR)
