The new solar abundances have been derived from analyses of the photospheric spectrum. They result from the use of a 3D hydrodynamical model of the solar atmosphere instead of the classical 1D hydrostatic models, accounting for departures from LTE when possible and improved atomic and molecular data. The new solar abundances are lower than previously recommended values and the present solar metallicity, Z, and Z/X, decrease to Z = 0.0122 and Z/X = 0.0165 respectively, almost a factor of two… Expand
