SEMINAR 2023

The analysis and interpretation of normal modes of oscillation in stars — asteroseismology — remains the only means by which the properties of stellar interiors may be measured directly. In particular, seismic rotational measurements, in the Sun and in other stars, provide constraints on the redistribution and transport of angular momentum, either as a result of stellar evolution, or arising from interactions with orbiting companions or other hydrodynamical instabilities. I provide a survey of existing observational techniques, and of key results accumulated over the past decade over the course of the NASA Kepler mission. I describe recent methodological developments enabling the inference of core-envelope misalignment — signifying interactions with misaligned orbital companions — and of magnetorotational signatures of fossil magnetic fields in stars hosting convective cores. Finally, I discuss the prospects for ensemble astrophysics enabled by these new techniques, in combination with both archival data from Kepler, as well as the NASA TESS and ESA PLATO missions.
