Authors: Rohit Sharma
Abstract: The Square Kilometer Array (SKA) will provide unprecedented quality data for solar sciences and space weather. The Sun is a plasma laboratory capturing a variety of plasma parameters and plays a pivotal role in space weather. Thus, solar activity, including eruptions like flares, coronal mass ejections, etc., is crucial. The radio wavelengths probe plasma systems from the solar surface to the corona from emission mechanisms like gyrosynchrotron, plasma emission, etc... These emissions are dynamic and variable in frequency and time, even during periods of low solar activity. The time-frequency and flux variability of the solar emission can span several orders of magnitude, depending on the phenomenon, magnetic topology and emission mechanism. The new-generation solar radio data, like Murchison Widefield Array, LOFAR, Meerkat, EOVSA and Jansky Very Large Array, have yielded high-sensitivity data of these variabilities. They have provided new insights into plasma diagnostics from the solar corona and eruptive phenomena like solar flares and coronal mass ejections. SKA solar observations will provide even more sensitive data and will improve plasma diagnostics. The talk will summarise the latest solar and heliophysics science cases and challenges with SKA.
