EUV Line Intensities and the Magnetic Field in Solar Active Regions [PDF]
Symposium - International Astronomical Union, 2001 The Coronal Diagnostic Spectrometer (CDS) on SOHO carries out daily synoptic observations of the Sun in four EUV (extreme ultraviolet) spectra: He I 584 Å, O V 630 Å, Mg IX 368 Å and Fe XVI 360 Å, over a 4 arcmin-wide strip along the solar central meridian.

Advanced Materials, EarlyView.Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

The Astrophysical JournalThe three-dimensional (3D) coronal magnetic field has not yet been directly observed. However, for a better understanding and prediction of magnetically driven solar eruptions, 3D models of solar active regions are required.

Advanced Materials, EarlyView.Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).

Dynamics of Subsurface Flows in Solar Active Regions during the 2024 May Storm
The Astrophysical JournalIn 2024 May, the Sun exhibited intense magnetic activity, marked by numerous high-intensity flares resulting from the interaction and merging of NOAA active regions (ARs) 13664 and 13668 in the southern hemisphere and AR 13663 in the northern hemisphere.

A Magnetic Pressure Difference Rule on Moving Bipolar Pores
The Astrophysical Journal LettersSolar pores are transient dark spots in the continuum images of the Sun. Their dynamics are closely associated with solar magnetic fields and plasma motion. Their motions have been found to be correlated with their magnetic pressure differences.

Changes of Magnetic Energy and Helicity in Solar Active Regions from Major Flares
The Astrophysical Journal, 2023 Magnetic free energy powers solar flares and coronal mass ejections, and the buildup of magnetic helicity might play a role in the development of unstable structures that subsequently erupt.
