"Turbulence " in the photosphere of the sun as a star. II. The general velocity field.
Abstract
A model of the general velocity field is applied to unresolvable (integral) weak line profiles over the solar disc. The profiles of weak lines are calculated in the emission flux of the sun as a star using the general velocity field (without discriminating micro- and macroturbulence). It is found that the amplitude of the general velocity field as large as 3 km sec-1 deduced from the profiles of weak lines has been essentially overestimated. It is shown that the calculation of profiles for strong as well as for moderate lines in the integral solar spectrum requires a separation of turbulent velocities into micro- and macrovelocities.
