Biography

Prof. Hava Turkakin has always been fascinated by the secret works of the universe and thus pursued a degree in Physics. She has a bachelor’s degree from the Black Sea Technical University in Turkey. After teaching several years at various high schools, her instant desire to learn more of physics has carried her to continue her education further. Hava earned her M.S. and Ph.D. in Space Physics from the University of Alberta. She has taught as a Visiting Assistant Professor at both Bucknell University and the University of Central Arkansas, before coming to Utica University. Her research interests are solar-terrestrial interactions, space weather, space plasmas, and plasma waves and instabilities in space. More specifically, Hava conducts research on Magnetohydrodynamic (MHD) waves and Instabilities along the boundaries formed during Solar-Terrestrial coupling. The basis of the solar-terrestrial coupling is the coupling of the large eruptions of plasma - called the solar wind – from the solar atmosphere to the earth’s magnetosphere – a magnetic bubble formed around the earth. Solar wind effects on the Earth’s magnetosphere, ionosphere and thermosphere can influence the performance and reliability of space-borne and ground-based technological systems and form the basis of space weather phenomenon.

Hava loves reading, taking a nature walk, and spending time with her children. In her most spare times, she loves watching Ellen show.

Opportunities for Student Research and Collaboration

Prof. Turkakin received a three-year award from National Science Foundation - Magnetospheric Physics. She is currently conducting research on “Instabilities and Wave Emissions in the Earth's Magnetosphere" with this support. Specifically, Prof. Turkakin investigates Bursty Bulk Flows (BBFs), which are fast flowing regions that form in the central magnetotail and may have profound impacts on the surrounding regions if they become unstable. Prof. Turkakin is working on a specific instability called Kelvin-Helmholtz Instability and possible emission of waves that may provide an effective mean of energy transportation out of these fast flowing regions. This in turn may have impacts on geomagnetic substorm dynamics.

Butler, S., Chen, W. and Turkakin, H., “Magnetohydrodynamic Modeling Investigations of Kelvin – Helmholtz Instability and Associated Magnetosonic Wave Emission Along Coronal Mass Ejections”,Astrophysical Journal, accepted, 2022

Tukakin, H., Rankin, R. and Mann, I.R., 2016, “Emission of Magnetosound From MHD Unstable Shear Flow Boundaries”, Journal of Geophysical Research, Vol. 121, doi:10.1002/2016JA022816

This paper shows the possibility of wave emission in various plasma shear flow boundaries as an effect of Kelvin-Helmholtz instability, an instability that develops along shear flow boundaries. This work only investigates into the linear regime of this instability, which we have extended in a work submitted in 2022.

This paper shows for the first time in the area of space research that often observed waves from an inner region of the Earth’s magnetosphere, the bubble formed by the interaction of the solar particles with the Earth’s magnetic field lines, may be due to the Kelvin-Helmholtz Instability. This paper has been chosen as a spotlight paper among the papers with innovative ideas by American Geophysical Union in 2014.

Tukakin, H., Rankin, R. and Mann, I.R., 2013, “Primary and Secondary Compressible Kelvin – Helmholtz Surface Wave Instabilities on the Earth's Magnetopause”, Journal of Geophysical Research, Vol. 118, 4161-4175, doi:10.1002/jgra.50394

This paper presents a detailed analysis of the occurrence of the Kelvin-Helmhotlz instabilities and conditions that makes them possible along the boundary of the Earth’s magnetosphere. We identified two types of Kelvin – Helmholtz instabilities as primary and secondary instabilities that occur at different shear flow speeds in this work. We investigated the types of waves that are emitted by this instability as well.

This paper shows the effects of wave trapping in the boundary of the Plasmasphere, which is another inner region of the Earth’s magnetosphere.
