Scientific paper

Stellar photospheric turbulence is discussed. Conceptualizations of turbulence are examined with attention to the micro-macroturbulence model and to models including mesoturbulence. Techniques are considered with reference to the curve of growth, line widths and shapes, Fourier transforms of line profiles, the separation of macroturbulence from rotation, and line shifts. Discussed topics relating to the behavior of turbulence across the HR diagram include microturbulence in main sequence stars, microturbulence in stars above the main sequence, macroturbulence in stars above the main sequence, the H and K connection, and turbulence and convection zones. Several physical aspects of turbulence are described.
