The Sun

Data: AGSS09 Solar Abundances

The reference composition of the Sun published in Asplund, Grevesse, Sauval & Scott (2009, Ann. Rev. Astron. & Astrophys. 47:481, arXiv:0909.0948) is available here. Below you can also find links to machine-readable ASCII versions of the two most important tables.

Table 1
Present-day solar photospheric elemental abundances, and CI meteoritic abundances. To obtain bulk/protosolar abundances, add 0.05 dex for He, 0.04 dex for heavier elements.

Table 3
Present-day representative solar isotopic composition.
