Equatorial waves and instabilities in astrophysical shear flows

磁场通常被认为是对剪切流的稳定影响，但事实并非总是如此。这个项目将研究磁场的增加如何改变潜在的纯流体动力流动的稳定性，在典型的应用中，这种流动已经受到旋转和密度分层的影响。重点将放在赤道气流上，那里经常有强大的射流，可能会变得不稳定。特别地，这个项目将扩展流体动力学赤道惯性不稳定性理论，以允许磁场。在了解行星和恒星大气层和内部的稳定性，以及了解热木星上赤道喷流的强度方面都有应用。

Magnetic fields are often thought to be a stabilising influence on shear flows, but this is not always the case. This project would investigate the ways in which the addition of magnetic fields can change the stability properties of the underlying purely hydrodynamic flows, which is already subject to rotation and density stratification in typical applications. The focus will be on equatorial flows, where there are often strong jets that can become hydrodynamically unstable. In particular, this project will extend the theory of hydrodynamic equatorial inertial instabilities to allow for magnetic fields. There are applications to understanding the stability of planetary and stellar atmospheres and interiors, and understanding the strength of equatorial jets on hot Jupiters.
