Applied mathematics seminar: Wave heating of the corona and solar wind
AlfvÃ©nic waves have long been considered a leading participant in the transfer of energy around cool, magnetised starsâ€™ atmospheres; potentially responsible for the heating of the Sunâ€™s corona and the acceleration of the solar wind. In the early 2000â€™s, various self-consistent models of AlfvÃ©nic wave turbulence from photosphere to heliosphere were developed that supported the role of wave dissipation. However, it wasnâ€™t until a few years later that AlfvÃ©nic waves were unambiguously observed in the Sunâ€™s corona, both in spectroscopic and imaging data. Since then, we have begun to probe the properties of the AlfvÃ©nic waves; providing key constraints for the wave turbulence heating models and challenging some of the long-held paradigms that these models rely upon. Here, I will discuss how ground-based observations of the corona in the Infrared are helping to uncover the behaviour of Alfvenic waves and the implications for our understanding of energy transfer via AlfvÃ©nic waves.
