The Solar Origin of an In Situ Type III Radio Burst Event

The Astrophysical Journal, 2023
Solar type III radio bursts are generated by beams of energetic electrons that travel along open magnetic field lines through the corona and into interplanetary space.

Coronal Transient Events During Two Solar Minima: Their Solar Source Regions and Interplanetary Counterparts

Solar Physics, 2011
In the frame of two coordinated observational and research efforts, two full solar rotations were investigated in the times of two distinct solar minima. These two campaigns were dubbed Whole Sun Month (WSM; 10 August – 8 September 1996) and Whole Heliosphere Interval (WHI; 20 March – 16 April 2008).

Damped large amplitude transverse oscillations in an EUV solar prominence, triggered by large-scale transient coronal waves [PDF]

Astronomy & Astrophysics, 2011
Aims. We investigate two successive trains of large amplitude transverse oscillations in an arched EUV prominence, observed with SoHO/EIT on the north-east solar limb on 30 July 2005. The oscillatory trains are triggered by two large scale coronal waves, associated with an X-class and a C-class flare occurring in the same remote active region.

Sequential Small Coronal Mass Ejections Observed In Situ and in White-Light Images by Parker Solar Probe

The Astrophysical Journal, 2023
We reconstruct the morphology and kinematics of a series of small transients that erupted from the Sun on 2021 April 24 using observations primarily from Parker Solar Probe (PSP). These sequential small coronal mass ejections (CMEs) may be the product of

The FIELDS Instrument Suite for Solar Probe Plus [PDF]

Space Science Reviews, 2016
NASA's Solar Probe Plus (SPP) mission will make the first in situ measurements of the solar corona and the birthplace of the solar wind. The FIELDS instrument suite on SPP will make direct measurements of electric and magnetic fields, the properties of in situ plasma waves, electron density and temperature profiles, and interplanetary radio emissions ...

Properties of Forbush Decreases with AMS-02 Daily Proton Flux Data

The Astrophysical Journal, 2023
A Forbush decrease (FD) is a sudden reduction of Galactic Cosmic Rays (GCRs) that is usually caused by intense solar wind transients, such as Interplanetary Coronal Mass Ejections (ICMEs) and Corotating Interaction Regions (CIRs).

On the importance of investigating CME complexity evolution during interplanetary propagation

Frontiers in Astronomy and Space Sciences, 2022
This perspective paper brings to light the need for comprehensive studies on the evolution of interplanetary coronal mass ejection (ICME) complexity during propagation. To date, few studies of ICME complexity exist.

Five-minute Periodicities in the Population of Solar Coronal Brightenings

The Astrophysical Journal
The population of small-scale brightenings observed across broad regions of the quiet-Sun (QS) corona shows coherent strong periodicities of ≈5 minutes and amplitudes of 20% to 30% of the mean.
