Surface Air Enrichment of Cosmogenic 35S at a Subtropical Site During the May 2024 Solar Superstorm

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Cosmogenic radiosulfur (35S) is produced in the atmosphere by high‐energy particle interactions and serves as a sensitive tracer of stratospheric intrusions. In May 2024, an extreme solar storm provided a rare opportunity to examine atmospheric 35S responses to intense solar activity.

Distorted Magnetic Flux Ropes within Interplanetary Coronal Mass Ejections

open access: yesThe Astrophysical Journal
Magnetic flux ropes (MFRs) at the center of interplanetary coronal mass ejections (ICMEs) are often characterized as simplistic cylindrical or toroidal tubes with field lines that twist around the cylinder or torus axis.

Two Energy Release Processes for CMEs: MHD Catastrophe and Magnetic Reconnection

open access: yes, 2007
It remains an open question how magnetic energy is rapidly released in the solar corona so as to create solar explosions such as solar flares and coronal mass ejections (CMEs).

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

open access: yesAstronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

Probing Velocity Dispersion Inside Coronal Mass Ejections: New Insights on Their Initiation

open access: yesThe Astrophysical Journal Letters
This work studies the kinematics of the leading edge and the core of six coronal mass ejections (CMEs) in the combined field of view of Sun Watcher using Active Pixel System detector and Image Processing (SWAP) on board PRoject for On-Board Autonomy ...

Solar Energetic Particles and Radio‐silent Fast Coronal Mass Ejections

open access: yesThe Astrophysical Journal, 2006
Both solar flares and shock waves driven by fast coronal mass ejections (CMEs) can accelerate charged particles in the solar corona and create transient enhancements of solar energetic particle fluxes in interplanetary space (SEP events). Fast CMEs and flares often occur together, which makes it difficult to directly identify the actual source of SEP ...

Strong Polar Ionospheric Electron Density Depletion Under Prolonged Northward IMF Bz Condition

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Previous studies have primarily focused on high‐latitude ionospheric‐thermospheric (I‐T) variabilities under southward interplanetary magnetic field (IMF) conditions, while rare studies have investigated the I‐T responses to due northward Bz (NBz), especially in the presence of strong IMF By conditions.

Coronal Loop Detection Using Multiscale Convolutional Neural Networks

open access: yesThe Astrophysical Journal Supplement Series, 2023
Solar magnetic fields play an important role in many solar activities, such as the solar wind, coronal mass ejections, and coronal oscillation. Coronal loops are curvilinear structures in the solar atmosphere and are closely related to coronal magnetic ...
