Description
Square Kilometer Array (SKA) will provide unprecedented quality data for solar sciences and space weather. Understanding space weather is vital for human space endeavours and territorial existence by avoiding space-based catastrophes. 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 ejection, etc., is crucial for understanding space weather.
The radio wavelengths catch various 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
These observed variabilities are due to weak energetic events requisite for nanoflare-based coronal and chromospheric heating theories.
The new-generation solar radio data like Murchison Widefield Array, LOFAR, Meerkat, EOVSA and Jansky Very Large Array supply high-sensitivity data, which provides an opportunity to probe plasma diagnostics from the solar corona and eruptive phenomena like solar flares and coronal mass ejections. The talk will summarise the latest various solar and heliophysics science cases and challenges with SKA.
