Disparities in Magnetic Cloud Observations between Two Spacecraft Having Small Radial and Angular Separations near 1 au

The Astrophysical Journal
Studies for inferring the global characteristics of coronal mass ejections (CMEs) from multipoint local in situ observations have been undertaken previously, but limited studies have utilized measurements from multiple spacecraft with sufficiently small ...

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.

Detecting Stellar Coronal Mass Ejections via Coronal Dimming in the Extreme Ultraviolet

The Astrophysical Journal
Stellar flares and coronal mass ejections (CMEs) can strip planetary atmospheres, reducing the potential habitability of terrestrial planets. While flares have been observed for decades, stellar CMEs remain elusive.

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.

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.

MHD Forecasting of Solar Wind With Coronal Mass Ejections

Space Weather
We present a model, implemented as an online service, for predicting the speed and density of solar wind in the inner heliosphere and near Earth. The model is based on a numerical magnetohydrodynamics code PLUTO.

3D Non-equilibrium Ionization and Spectroscopic Modeling of Coronal Mass Ejections. II. CME Energy Budget

The Astrophysical Journal
Coronal mass ejections (CMEs) release between ≈10 ^30 and 10 ^33 erg of energy into the corona; however, their detailed energy budget is difficult to constrain.

Data-driven magnetohydrodynamic simulation of the initiation of a coronal mass ejection with multiple stages

Astronomy & Astrophysics
Coronal mass ejections (CMEs) are the primary drivers of adverse space-weather events, yet their initiation and onset prediction remain insufficiently understood due to the complexity of the magnetic topology and physical processes in real solar source ...

Discrepancies in the Properties of a Coronal Mass Ejection on Scales of 0.03 au as Revealed by Simultaneous Measurements at Solar Orbiter and Wind: The 2021 November 3–5 Event

The Astrophysical Journal
Simultaneous in situ measurements of coronal mass ejections (CMEs), including both plasma and magnetic field, by two spacecraft in radial alignment have been extremely rare.
