Recent discoveries in solar and stellar physics highlight the role of inertial modes —global oscillations restored by the Coriolis force— in probing internal stellar structure and dynamics. On the Sun, these modes have been observed in long time series of horizontal flow maps and modeling efforts have provided insights into their rich spectrum. In particular, high-latitude inertial modes are baroclinically unstable and control a 7 K pole-to-equator temperature contrast in the convective envelope consistent with thermal wind balance.<\/p>\n
In intermediate-mass stars, gravito-inertial modes —shaped by both buoyancy and rotation— have been observed by Kepler<\/em> in \u03b3-Doradus pulsators. For moderate to rapid stellar rotation, Rossby (r) modes appear just below multiples of the stellar rotation frequency. Additionally, pure inertial modes in convective cores have been inferred from a characteristic resonance signature in gravito-inertial mode spectra, providing direct constraints on core rotation and stratification. Across a broader sample of intermediate-mass stars, a \u201chump and spike\u201d feature has been detected in oscillation power spectra, likely linked to unresolved r modes and stellar activity.<\/p>\n These findings establish inertial modes as key tools for understanding stellar interiors, rotation, and magnetic activity. In particular, they offer new insights into the still-mysterious nature of convection in solar and stellar interiors. Research on these modes has so far progressed largely independently in the solar and stellar communities. With this ISSI Team, we propose uniting key researchers from both fields to exchange expertise, foster collaborations, and advance joint research.<\/p>\n","protected":false},"excerpt":{"rendered":" Recent discoveries in solar and stellar physics highlight the role of inertial modes —global oscillations restored by the Coriolis force— in probing internal stellar structure and dynamics.
