Radiation Processes and models
Julian Malzac (University of Toulouse, France)

Lesson 1:  Introduction to compact objects:  The sources of power

• Rotation (pulsars)
• Magnetic fields (Magnetars)
• Gravitation (basics of accretion in binary system with a compact star/BH)
• mass transfer
• accretion flows (hot vs cold) and interaction with compact star (magnetised vs unmagnetised, hard surface vs no surface)
• jet launching
• Thermo-nuclear (Novae/X-ray bursters)

Lesson 2:   Radiation processes:

• Cyclo-synchrotron
• Curvature radiation
• Compton
• Bremstrahlung
• Electron/positron pair production and annihilation

Lesson 3:  Models for the variable multi-wavelength emission of black hole binaries: accretion flow

• the structure of inner accretion flow inferred from X-ray spectral modelling
• the most popular model for the X-ray fast variability and QPOs
• fast optical variability from the accretion flow:
  • disk reprocessing
  • synchrotron emission
• from non-thermal particles in the hot corona
• optical QPOs  from the accretion flow

Lesson 4:  Models for the variable multi-wavelength emission of black hole binaries:  compact jets

• standard jet spectral model and the problem of dissipation jets
• the internal shock model: multi-wavelength spectral and timing properties
• IR/optical QPOs from jet precession
• IR/opt/X-ray fast timing correlations as a probe for the coupled
• dynamics of accretion and ejection
