Role of SKA in Advancing Remote Measurements of Magnetic Fields of Solar Coronal Mass Ejections
Devojyoti Kansabanik, Surajit Mondal, Shaheda Begum Shaik +13
Coronal Mass Ejections (CMEs) are large expulsions of magnetized plasma from the Sun into interplanetary space and are the primary drivers of extreme space weather variations. The…
Unravelling the nonthermal emissions from the quiet solar corona with the SKA
Surajit Mondal, Divya Oberoi, Rohit Sharma +4
Investigation of the nonthermal emissions from the quiet solar corona has been rather limited. This primarily stems from the fact that the emission is expected to be quite weak and…
State-of-the-art Observation, Calibration, and Imaging Framework for Solar and Heliospheric Sciences with SKA
Divya Oberoi, Devojyoti Kansabanik, Soham Dey +6
The Sun is a surprisingly difficult radio source to observe and image, even with the SKA. It is multiple orders brighter than the typical radio sources, which sensitive radio teles…
Radio Spectral Imaging and MHD Modeling of a CME-Driven Shock: Connecting Solar Type II Radio Bursts with Shock-Surface Magnetic Geometry
Peijin Zhang, Weihao Liu, Bin Chen +3
Solar type II radio bursts are widely regarded as signatures of shock waves propagating in the solar corona and are of particular importance for understanding shock-driven particle…
Modeling the Thermal Low-Frequency Radio Sun with Ray Tracing
Peijin Zhang, Bin Chen, Gregory Fleishman +4
Incoherent radio emission at meter--decimeter wavelengths provides a key diagnostic of the coronal thermal plasma, but at frequencies below \,1\,GHz coronal refraction can su…
A 44-minute periodic radio transient in a supernova remnant
Di Li, Mao Yuan, Lin Wu +45
Long-period radio transients (LPTs) are a newly discovered class of radio emitters with periods ranging from minutes to hours. The astrophysical nature remains undetermined, partic…
