Comparison of Exact and Approximate MHD Slow Body Mode Solutions in Photospheric Waveguides

In this study, we explore the possibility of simplifying the modeling of magnetohydrodynamic slow body modes observed in photospheric magnetic structures such as the umbrae of sunspots and pores. The simplifying approach assumes that the variation of the eigenvalues of slow body waves can be derived...
