ARE THE FAINT STRUCTURES AHEAD OF SOLAR CORONAL MASS EJECTIONS REAL SIGNATURES OF DRIVEN SHOCKS?

open access: yesThe Astrophysical Journal, 2014
Recently, several studies have assumed that the faint structures ahead of coronal mass ejections (CMEs) are caused by CME-driven shocks. In this study, we have conducted a statistical investigation to determine whether or not the appearance of such faint structures depends on CME speeds.

Space Weather in the Saturn–Titan System

open access: yesThe Astrophysical Journal, 2023
New evidence based on Cassini magnetic field and plasma data has revealed that the discovery of Titan outside Saturn’s magnetosphere during the T96 flyby on 2013 December 1 was the result of the impact of two consecutive interplanetary coronal mass ...

Coronal mass ejection kinematics deduced from white light (Solar Mass Ejection Imager) and radio (Wind/WAVES) observations [PDF]

open access: yes, 2005
International audienceWhite-light and radio observations are combined to deduce the coronal and interplanetary kinematics of a fast coronal mass ejection (CME) that was ejected from the Sun at about 1700 UT on 2 November 2003.

Comparison of the coronal mass ejection shock acceleration of three widespread SEP events during solar cycle 24 [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2017
AbstractWe studied three solar energetic particle (SEP) events observed on 14 August 2010, 3 November 2011, and 5 March 2013 by Solar Terrestrial Relations Observatory (STEREO) A, B, and near‐Earth (L1) spacecraft with a longitudinal distribution of particles >90°.

Radial distributions of magnetic field strength in the solar corona as derived from data on fast halo CMEs

open access: yesSolar-Terrestrial Physics, 2018
In recent years, information about the distance between the body of rapid coronal mass ejection (CME) and the associated shock wave has been used to measure the magnetic field in the solar corona.

Treatment of Viscosity in the Shock Waves Observed After Two Consecutive Coronal Mass Ejection Activities CME08/03/2012 and CME15/03/2012 [PDF]

open access: yes, 2016
A coronal mass ejection (CME) is one of the most the powerful activities of the Sun. There is a possibility to produce shocks in the interplanetary medium after CMEs.

Near-Sun In Situ and Remote-sensing Observations of a Coronal Mass Ejection and its Effect on the Heliospheric Current Sheet

open access: yesThe Astrophysical Journal, 2023
During the thirteenth encounter of the Parker Solar Probe (PSP) mission, the spacecraft traveled through a topologically complex interplanetary coronal mass ejection (ICME) beginning on 2022 September 5.

Simulated enhancement of solar type II radio bursts during the collision of two shocks associated with coronal mass ejections [PDF]

open access: yesAstronomy & Astrophysics, 2006
Aims. We investigate how solar type II radio bursts can be enhanced when two fast magnetosonic shocks associated with coronal mass ejections (CMEs) collide. This work was motivated by recent observations showing that the radio signature is in the form of intense continuum-like radio emission following an interplanetary type II burst, when a fast CME ...

Shock-accelerated electrons during the fast expansion of a coronal mass ejection [PDF]

open access: yes, 2022
Context. Some of of the most prominent sources for energetic particles in our Solar System are huge eruptions of magnetised plasma from the Sun called coronal mass ejections (CMEs), which usually drive shocks that accelerate charged particles up to ...
