Scientific paper

The sensitivity to changes in the interior opacities of a number of solar parameters commonly inferred from standard solar models is investigated. In particular, the sensitivity of the central temperature, the radius at the base of the convective zone, and the degree of lithium depletion to changes in the opacity prescription are discussed. The impact of the new OPAL opacities on these quantities is examined, and it is found that further interior opacity increases concentrated around 2 x 10 exp 6 K are indicated from the solar oscillation data. Some additional OPAL opacities needed to produce accurate standard solar models are provided.
