Line formation in solar granulation VI. [C I], C I, CH and C2 lines and the photospheric C abundance
M. Asplund, N. Grevesse, A. J. Sauval +2
The solar photospheric carbon abundance has been determined from [C I], C I, CH vibration-rotation, CH A-X electronic and C2 Swan electronic lines by means of a time-dependent, 3D,…
The solar chemical composition
Martin Asplund, Nicolas Grevesse, Jacques Sauval
We review our current knowledge of the solar chemical composition as determined from photospheric absorption lines. In particular we describe the recent significant revisions of th…
Solar model with CNO revised abundances
J. Montalban, A. Miglio, A. Noels +3
Recent three-dimensional, NLTE analyses of the solar spectrum have shown a significant reduction in the C, N, O and Ne abundances leading to a Z/X ratio of the order of 0.0177. We…
