The Influence of Low-Temperature Opacity on Solar Models and p-Mode Frequencies
Abstract
The opacity is one of the leading input physics quantities that may influence the structure and p-mode frequencies of the sun. Although the most important opacity contribution on a solar model is the atomic and ionic contribution in the interior, the influence of the outside low-temperature opacity is also relevant. Presently, the low-temperature opacity has a somewhat higher uncertainty than the one of the interior, and this difference may influence more on high order p-modes, which spend most of their life traveling through the low-temperature opacity region. In this work we test the sensitivity of solar structure and frequencies with some up-to-date, well accepted low-temperature opacities.
