A magnetohydrodynamic mechanism for the formation of solar polar vortices
M Dikpati, B Raphaldini, SW McIntosh… - Proceedings of the …, 2024 - pnas.org
Polar vortices are ubiquitous features of planetary atmospheric flows, from the Earth-like
rocky planets to Jupiter-and Saturn-like gas giant planets. Very little is known about their …

Solar Inertial Modes
The Sun's global inertial modes are very sensitive to the solar differential rotation and to
properties of the deep solar convection zone which are currently poorly constrained. These …

Inversion for Inferring Solar Meridional Circulation: The Case with Constraints on Angular Momentum Transport inside the Sun
Y Hatta, H Hotta, T Sekii - arXiv preprint arXiv:2406.12077, 2024 - arxiv.org
We have carried out inversions of travel times as measured by Gizon et al.(2020) to infer the
internal profile of the solar meridional circulation (MC). A linear inverse problem has been …

A common law for the differential rotation of planets and stars
VGA Böning, J Wicht - arXiv preprint arXiv:2407.13484, 2024 - arxiv.org
All planets and stars rotate. All gas planets in our solar system, the Sun, and many stars
show a pattern of east-or westward mean flows. This phenomenon is known as differential …
