The solar core: new low-l p-mode fine-spacing results from BiSON

W. J. Chaplin, Y. Elsworth, G. R. Isaak +3

The fine-structure spacing $d_{\ell }(n)={\nu }_{\ell ,n}-{\nu }_{\ell +2,n-1}$ for low-degree solar p modes of angular degree $\ell$ and radial order n, is sensitive to conditions in the d…
