Line formation in solar granulation VI. [Cl], Cl, CH and C2 lines and the photospheric C abundance

Asplund, Martin; Grevesse, N; Sauval, A J; Prieto, Carlos Allende; Blomme, R


The solar photospheric carbon abundance has been determined from [C I], CI, CH vibration-rotation, CH A-X electronic and C2 Swan electronic lines by means of a time-dependent, 3D, hydrodynamical model of the solar atmosphere. Departures from LTE have been considered for the CI lines. These turned out to be of increasing importance for stronger lines and are crucial to remove a trend in LTE abundances with the strengths of the lines. Very gratifying agreement is found among all the atomic and...[Show more]
