Autor: Devojyoti Kansabanik, Surajit Mondal, Divya Oberoi, James O. Chibueze, N. E. Engelbrecht, R. D. Strauss, E. P. Kontar, G. J. J. Botha, P. J. Steyn, Amoré E. Nel

Publikováno v: The Astrophysical Journal, Vol 961, Iss 1, p 96 (2024)

Solar radio emissions provide several unique diagnostics to estimate different physical parameters of the solar corona, which are otherwise simply inaccessible. However, imaging the highly dynamic solar coronal emissions spanning a large range of ang

Imaging spectroscopy of solar radio burst fine structures

Autor: E. P. Kontar, S. Yu, A. A. Kuznetsov, A. G. Emslie, B. Alcock, N. L. S. Jeffrey, V. N. Melnik, N. H. Bian, P. Subramanian

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-9 (2017)

Radio observations of the solar atmosphere provide a unique view on the non-thermal processes in the outer atmosphere. Here the authors use LOFAR observations to demonstrate that the observed radio burst characteristics are dominated by propagation e

An optical study of multiple NEIAL events driven by low energy electron precipitation

Autor: J. M. Sullivan, M. Lockwood, B. S. Lanchester, E. P. Kontar, N. Ivchenko, H. Dahlgren, D. K. Whiter

Publikováno v: Annales Geophysicae, Vol 26, Pp 2435-2447 (2008)

Optical data are compared with EISCAT radar observations of multiple Naturally Enhanced Ion-Acoustic Line (NEIAL) events in the dayside cusp. This study uses narrow field of view cameras to observe small-scale, short-lived auroral features. Using

Turbulent Kinetic Energy in the Energy Balance of a Solar Flare

Autor: E P, Kontar, J E, Perez, L K, Harra, A A, Kuznetsov, A G, Emslie, N L S, Jeffrey, N H, Bian, B R, Dennis

Publikováno v: Physical review letters. 118(15)

The energy released in solar flares derives from a reconfiguration of magnetic fields to a lower energy state, and is manifested in several forms, including bulk kinetic energy of the coronal mass ejection, acceleration of electrons and ions, and enh
