摘要：

We determine the gravitational multipole moments J(2n); n = 1; 5, of the sun using a model of the interior structure and of solar rotation obtained from helioseismic inversions. The differential rotation of the convective zone and the underlying transition zone make only a small (approximate to 0.5%) contribution to the quadrupole moment J(2) which is found to have a value approximate to 2.21 x 10(-7).
