Line formation in solar granulation: II. The photospheric Fe abundance

Asplund, Martin; Nordlund, A; Trampedach, R; Stein, Robert F

Description

The solar photospheric Fe abundance has been determined using realistic ab initio 3D, time-dependent, hydrodynamical model atmospheres. The study is based on the excellent agreement between the predicted and observed line profiles directly rather than equivalent widths, since the intrinsic Doppler broadening from the convective motions and oscillations provide the necessary non-thermal broadening. Thus, three of the four hotly debated parameters (equivalent widths, microturbulence and damping...[Show more]
