Detection of a Magnetic Discontinuity in the Upper Solar Chromosphere Associated with a Coronal Loop Brightening Observed by CLASP2.1

The Astrophysical Journal
We report the first detection of a magnetic discontinuity in the upper solar chromosphere associated with a coronal loop brightening. Our findings are based on novel observations obtained by the Chromospheric LAyer SpectroPolarimeter (CLASP2.1 ...

Multiple shocks generated by the 2024 May 14 coronal mass ejection

Astronomy & Astrophysics
Context. A series of powerful solar flares and coronal mass ejections (CMEs) occurred between 10 and 14 May 2024. As these eruptions propagated through the corona, they generated multiple solar type II radio bursts, indicating the presence of shock waves.

Deciphering the Formation and Dynamics of Double-decker Filaments through Component Magnetic Reconnection

The Astrophysical Journal Letters
The formation of double-decker filaments has long been an enigma in the field of solar physics. Using stereoscopic observations from the Solar Dynamics Observatory and the Solar Terrestrial Relations Observatory, we show that the double-decker filament ...

A New Field Line Tracer for the Study of Coronal Magnetic Topologies

The Astrophysical Journal
We present a new code for the tracing of magnetic field lines and calculation of related quantities such as the squashing factor in the solar corona.

Mixed Source Region Signatures inside Magnetic Switchback Patches Inferred by Heavy Ion Diagnostics

The Astrophysical Journal
Since Parker Solar Probe’s (Parker’s) first perihelion pass at the Sun, large-amplitude Alfvén waves grouped in patches have been observed near the Sun throughout the mission.

Proposed Resolution to the Solar Open Magnetic Flux Problem

The Astrophysical Journal
The solar magnetic fields emerging from the photosphere into the chromosphere and corona are comprised of a combination of closed (field lines with both ends rooted at the Sun) and open (field lines with only one end at the Sun) fields.
