【 摘 要 】

We revisit the issue of solar abundances and examine whether the updated abundances result in solar models that have structures that agree with the structure of the Sun as determined by helioseismology. We quantify the changes in opacity required to bring the models constructed with the newer solar abundances in agreement with the Sun.
