Slow shocks in coronal mass ejections [PDF]

open access: yes
The possibility that slow-mode shock compression may produce at least some of the increased brightness observed at the leading edge of coronal mass ejections is investigated.

MHD Forecasting of Solar Wind With Coronal Mass Ejections

open access: yesSpace 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

open access: yesThe 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.

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

open access: yesThe 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.

Driving Dynamical Inner‐Heliosphere Models With In Situ Solar Wind Observations

open access: yesSpace Weather
Accurately reconstructing the solar wind throughout the inner heliosphere is essential for understanding solar–terrestrial interactions and improving space‐weather forecasts.

The ap Prediction Tool Implemented by the A.Ne.Mo.S./NKUA Group

open access: yesAtmosphere
A novel tool utilizing machine learning techniques was designed to forecast ap index values for the next three consecutive days (24 values). The tool employs time series data from the 3 h ap index of solar cycles 23 and 24 to train the Long Short-Term ...

Initiation Route of Coronal Mass Ejections. II. The Role of Filament Mass

open access: yesThe Astrophysical Journal
A thorough understanding of the initiation of coronal mass ejections (CMEs), which is manifested as a slow rise of pre-eruptive structures before the impulsive ejection in kinematics, is key for forecasting solar eruptions.
