Physical Processes Definitions Sources of Opacity Hydrogen bf and ff H - H 2 He Scattering. How does k n affect the spectrum? More continuous absorption, less continuum light at that wavelength More continuous absorption, lines must form in shallower layers, at lower optical depth

Free-Free Absorption from H I

Free-Free Absorption from H I. Much less than bf absorption Kramers (1923) + Gaunt (1930) again Absorption coefficient depends on the speed of the electron (slower electrons are more likely to absorb a photon because their encounters with H atoms take longer)
