Multi-Wavelength Diagnostics of Pre-Flare Evolution with Aditya-L1: From the Solar Chromosphere to the Corona

Adithya H. N., Sreejith Padinhatteeri, Soumya Roy +13

The pre-flare phase of solar flares provides important insight into the processes that drive active regions toward instability. We investigate chromospheric pre-flare activity usin…

Evolution of Non-Stationary Quasi-Periodic Pulsations in Solar Flares with Aditya-L1/HEL1OS and GOES

Srikar Paavan Tadepalli, Abhishekh Kumar Srivastava, K. Sankarasubramanian

In the present work, we use a phase-resolved methodology for the detection and characterisation of non-stationary QPPs in the hard X-ray lightcurves observed from the HEL1OS instru…

Iron Fluorescence in X-class Solar Flares: Aditya-L1/SoLEXS Observations

Abhilash R. Sarwade, K. Sankarasubramanian, Monoj Bug +5

Iron fluorescence is produced by the irradiation of the solar photosphere by coronal X-rays during flares. This study presents the first comprehensive analysis of iron K fluore…
