Elemental Composition Evolution during the 2024 September 30 Solar Eruption: A Comparison of Hot and Cool Plasma Components with Solar Orbiter/SPICE, Hinode/EIS, and Chandrayaan-2/XSM

Momchil Molnar, Joseph Plowman, Amir Caspi +7

Solar plasma composition differs between the photosphere and corona over a range of timescales, with preferential enhancement of elements with low first ionization potential (FIP).…

Neural Enhancement of the Traditional Wang-Sheeley-Arge Solar Wind Relation

Prateek Mayank, Enrico Camporeale, Arpit K. Shrivastav +2

The Wang-Sheeley-Arge (WSA) model has been the cornerstone of operational solar wind forecasting for nearly two decades, owing to its simplicity and physics-based formalism. Howeve…

Co-existence of longitudinal and transverse oscillations in polar plumes observed with Solar Orbiter/EUI

Upasna Baweja, Vaibhav Pant, S. Krishna Prasad +6

Magnetohydrodynamic (MHD) waves play a key role in heating the solar corona and driving the solar wind. Recent observations have shown the presence of slow magneto-acoustic and Alf…

Dynamics of Reconnection Nanojets in Eruptive and Confined Solar Flares

Annu Bura, Arpit Kumar Shrivastav, Ritesh Patel +6

Recent observations reveal small-scale reconnection-driven plasma ejections, often termed nanojets, triggered by magnetic field interactions at slight misalignment angles. These fa…

On the Existence of Long-Period Decayless Oscillations in Short Active Region Loops

Arpit Kumar Shrivastav, Vaibhav Pant, Rohan Kumar +5

Decayless kink oscillations, characterized by their lack of decay in amplitude, have been detected in coronal loops of varying scales in active regions, quiet Sun and coronal holes…
