Line Formation in Solar Granulation IV. [O1], O1 and OH lines and the photospheric O abundance
The solar photospheric oxygen abundance has been determined from [O I], O I, OH vibration-rotation and OH pure rotation lines by means of a realistic time-dependent, 3D, hydrodynamical model of the solar atmosphere. In the case of the O I lines, 3D non-LTE calculations have been performed, revealing significant departures from LTE as a result of photon losses in the lines. We derive a solar oxygen abundance of log εo = 8.66 ± 0.05. All oxygen diagnostics yield highly consistent abundances, in...[Show more]
