Synthetic spectra show that observational biases cause dipole mode visibilities to be overestimated by up to 20 percent on the red-giant branch, while partial energy preservation under magnetic damping can produce both present and absent mixed-mode signatures.
MESA grids show global magnetic sensitivity in red giants depends on mass and metallicity and can be recovered to 10% uncertainty with accurate spectroscopic metallicity.
Overview of asteroseismology principles, data needs, forward modeling methods, key results across the HR diagram, and future challenges.
