About this award
The University of Colorado, through its Office of Contracts and Grants, received a $824,943 research grant awarded January 1, 2024, by a civilian federal agency with an ultimate completion date of December 31, 2026. This grant supports the development of seismic diagnostic tools to study the Sun's inertial modes, advancing heliophysics research through computational and theoretical methods. The project employs three complementary approaches: three-dimensional nonlinear numerical simulations using the open-source Rayleigh code, linear eigenmode calculations in spherical geometry using the Dedalus code, and semi-analytic wave-propagation models in simplified geometries. The linear eigenmode work will enable mode classification and spatial characterization of eigenfunctions, while nonlinear simulations will provide critical information about mode excitation and amplitudes. The wave propagation models will support development of perturbative inversion techniques to extract scientific insights from the numerical results.
This research addresses fundamental science questions outlined in the 2013–2022 Decadal Survey in Solar and Space Physics, specifically targeting the origins of solar activity and characterization of fundamental processes within the heliosphere and universe. By leveraging novel observations of the Sun's inertial modes, the project will develop seismic tools to probe subsurface solar regions currently inaccessible to direct observation—the same regions likely to control the solar dynamo. The work is being performed in Boulder, Colorado, and represents a parent contract with no set-aside designation, demonstrating competitive merit-based selection for this fundamental solar physics research.
