Constraining the Mass Loss and the Kinetic Energy of Stellar Coronal Mass Ejections with Solar Far-ultraviolet Flares

The Astrophysical Journal
Stellar eruptive events, such as flares and coronal mass ejections (CMEs), can affect planetary habitability by disturbing the stability of their atmospheres.

Ionosphere‐Thermosphere Coupling in the Northern Polar Region During the May 2024 Geomagnetic Superstorm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The May 2024 superstorm, as the most intense geomagnetic storm since 2003, caused a variety of disturbances in the magnetosphere‐ionosphere‐thermosphere system. This study investigates the long‐lasting electron density depletion in the polar region and the underlying ionosphere‐thermosphere coupling, based on a comprehensive set of ...

Role of coronal mass ejections in the heliospheric Hale cycle [PDF]

, 2007
[1] The 11-year solar cycle variation in the heliospheric magnetic field strength can be explained by the temporary buildup of closed flux released by coronal mass ejections (CMEs).

Segmentation and Tracking of Eruptive Solar Phenomena With Convolutional Neural Networks

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Solar eruptive events are complex phenomena, which most often include coronal mass ejections (CME), CME‐driven compressive and shock waves, flares, and filament eruptions. CMEs are large eruptions of magnetized plasma from the Sun's outer atmosphere or corona, that propagate outward into the interplanetary space.

MAVEN EUVM Data Products for Space Weather at Mars

Space Weather, Volume 24, Issue 2, February 2026.
Abstract Space weather monitoring is critical to protect not only our technological assets in space, but also mitigate disruptions to life and society that depends on these vulnerable assets. Significant attention and resources have been dedicated to space weather monitoring at Earth, but little attention to date has been paid to planetary space ...

High‐Latitude Electrodynamics and Thermospheric Density Variations During the 2024 Gannon Storm

Space Weather, Volume 24, Issue 2, February 2026.
Abstract This study investigates high‐latitude electrodynamics and thermospheric density variations during the 2024 Gannon's storm. First, the auroral precipitation module of Auroral Spectra and High‐Latitude Electric field variabilitY, ASHLEY‐A, is improved to more accurately capture the location of auroral precipitation observed during this ...

Two classes of solar energetic particle events associated with impulsive and long duration soft X-ray flares [PDF]

Solar energetic particle events observed in space have different properties depending on the class of associated flare. Impulsive flares, which occur low in the corona in regions of high energy density, are associated with particle events which are ...

The Non‐Linear Dependence of Daily Maximum Ionospheric Total Electron Content on F10.7

Space Weather, Volume 24, Issue 2, February 2026.
Abstract Daily 10.7 cm solar flux, the F10.7 index, is a key parameter for the ionospheric state. Global maps of ionospheric Total Electron Content (TEC) offer almost continuous multidecadal coverage. We find that the global daily maximum of TEC saturates with daily F10.7.

Sustainable bioceramics, biopolymers, and composites for bone applications: From bench to production

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract In response to environmental challenges and primary resource scarcity, sustainable approaches that rely on recycling and reusing waste materials are becoming highly valuable and appealing options in modern society. These strategies have started being applied in biomaterials science, too, leading to the advent of new synergies between ...

Characteristics of coronal mass ejections in the near Sun interplanetary space [PDF]

Geofísica Internacional, 2004
Based on the observations from the Large Angle and Spectrometric Coronagraph (LASCO) on board the Solar and Heliospheric Observatory (SOHO) spacecraft we studied coronal mass ejections (CME) parameters between 6 and 10 solar radii from the Sun.
