3D reconstruction of coronal loops by the principal component analysis [PDF]

, 2013
Knowing the three dimensional structure of plasma filaments in the uppermost part of the solar atmosphere, known as coronal loops, and especially their length, is an important parameter in the wave-based diagnostics of this part of the Sun.

The Origin of Energetic Solar Protons: Comparative Analysis of Ground-level Enhancement (GLE) Events and Non-GLE Solar Energetic Particle Events

The Astrophysical Journal Supplement Series
This study explores the acceleration origins of solar energetic particles (SEPs) by analyzing the energy spectral characteristics of particles in ground-level enhancement (GLE) events and common SEP (non-GLE) events, as well as the correlations of the ...

Large-scale Globally Propagating Coronal Waves

Living Reviews in Solar Physics, 2015
Large-scale, globally propagating wave-like disturbances have been observed in the solar chromosphere and by inference in the corona since the 1960s. However, detailed analysis of these phenomena has only been conducted since the late 1990s.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Radio Signature of the Strong Compression between a Streamer and a Coronal Hole Boundary

The Astrophysical Journal Letters
We present evidence of the first detection of the radio signature at metric wavelengths of the strong compression between a helmet streamer (HS) and the boundary of a coronal hole (CH) using radio observations from the Callisto MEXICO-LANCE and ALASKA ...

Theta Aurora: Transpolar Arcs Linked to a Folded Magnetotail Neutral Sheet

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Nightside‐originating transpolar arcs (TPAs) represent a distinct mechanism of magnetosphere‐ionosphere energy transfer during northward IMF conditions. Nightside‐originating TPAs originate from the nightside auroral oval and grow across the polar cap to connect to the dayside, appearing to cross multiple topological boundaries as they develop.

STEREO DIRECT IMAGING OF A CORONAL MASS EJECTION-DRIVEN SHOCK TO 0.5 AU [PDF]

, 2011
Fast coronal mass ejections (CMEs) generate standing or bow shocks as they propagate through the corona and solar wind. Although CME shocks have previously been detected indirectly via their emission at radio frequencies, direct imaging has remained ...

The interplanetary causes of geomagnetic activity during the 7–17 March 2012 interval: a CAWSES II overview

Journal of Space Weather and Space Climate, 2014
This overview paper presents/discusses the major solar, interplanetary, magnetospheric, and ionospheric features of the CAWSES II interval of study: 7–17 March 2012. Magnetic storms occurred on 7, 9, 12, and 15 March with peak SYM-H intensities of −98 nT,

Tracing solar wind plasma entry into the magnetosphere using ion-to-electron temperature ratio [PDF]

, 2009
When the solar wind Mach number is low, typically such as in magnetic clouds, the physics of the bow shock leads to a downstream ion-to-electron temperature ratio that can be notably lower than usual.

Limb Observations of Global Solar Coronal Extreme-ultraviolet Wavefronts: The Inclination, Kinematics, Coupling with the Expanding Coronal Mass Ejections, and Connection with the Coronal Mass Ejection Driven Shocks

The Astrophysical Journal
We select and investigate six global solar extreme-ultraviolet (EUV) wave events using data from the Solar Dynamics Observatory and the Solar and Heliospheric Observatory.
