Chromospheric dynamics and turbulence regulate the solar FIP effect
Announce Type: replace-cross Abstract: Elemental abundance variations in the solar corona, commonly characterised by First Ionisation Potential (FIP) bias, provide crucial diagnostics of chromospheric processes. The ponderomotive force model, which attributes fractionation to Alfv\'en wave propagation, has successfully reproduced the observed fractionation patterns in various solar features. However, existing theoretical implementations rely on a static quiet Sun chromosphere, leaving the...
Fast Radio Bursts produced during collapse of macroscopic X-mode in magnetized pair plasma
arXiv:2606.09417v1 Announce Type: cross Abstract: We demonstrate that in highly magnetized pair plasma nonlinear long-wavelength X-modes experience wave collapse/breaking, whereby the wave undergoes severe spatial steepening, driven by nonlinear modifications of the refractive index and strong ponderomotive forces. The collapse/wave breaking occurs in a narrow parameter regime, when the fluctuating part of the magnetic field exceed the guide field, and plasma magnetization is close to the...
