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

, 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).

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.

The Power of a Name: Toward a Unified Approach to Naming Space Weather Events

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Our increasing reliance on technology vulnerable to space weather effects underscores the urgent need for effective public communication about these phenomena. While scientific research thrives on precise technical language, broader public engagement necessitates a more accessible and memorable approach.

Can solar wind viscous drag account for CME deceleration?

, 2012
The forces acting on solar Coronal Mass Ejections (CMEs) in the interplanetary medium have been evaluated so far in terms of an empirical drag coefficient $C_{\rm D} \sim 1$ that quantifies the role of the aerodynamic drag experienced by a typical CME ...

Anomalous expansion of coronal mass ejections during solar cycle 24 and its space weather implications [PDF]

, 2014
The familiar correlation between the speed and angular width of coronal mass ejections (CMEs) is also found in solar cycle 24, but the regression line has a larger slope: for a given CME speed, cycle 24 CMEs are significantly wider than those in cycle 23.

Properties of Earthward and Tailward High‐Speed Plasma Flows in Earth's Distant Magnetotail: Solar Cycle and Geomagnetic Activity Dependence

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract High‐speed plasma flows in Earth's magnetotail are important for the global dynamics of the magnetosphere. We survey 11 yrs of high‐speed plasma flows observed by the ARTEMIS spacecraft in Earth's distant magnetotail between XGSE = −52 RE and XGSE = −66 RE to investigate their properties for a wide range of solar and geomagnetic activity ...

A Comparison of MAVEN SIR Observations With the Stationary WSA‐ENLIL Solar Wind Model

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract Predicting times of arrival and properties of space weather events, such as coronal mass ejections and stream interaction regions (SIRs), has become an important focus of the space physics community within recent years. Extensive efforts have been undertaken to model these space weather events throughout the heliosphere in order to better ...

On flare-CME characteristics from Sun to Earth combining remote-sensing image data with in-situ measurements supported by modeling

, 2017
We analyze the well observed flare-CME event from October 1, 2011 (SOL2011-10-01T09:18) covering the complete chain of action - from Sun to Earth - for a better understanding of the dynamic evolution of the CME and its embedded magnetic field.
