The Effect of the Parametric Decay Instability on the Morphology of Coronal Type III Radio Bursts
Chaitanya Prasad Sishtla, Immanuel Christopher Jebaraj, Jens Pomoell +4
The nonlinear evolution of Alfvén waves in the solar corona leads to the generation of Alfvénic turbulence. This description of the Alfvén waves involves parametric instabilities w…
Connecting remote and in situ observations of shock-accelerated electrons associated with a coronal mass ejection
D. E. Morosan, J. Pomoell, C. Palmroos +7
One 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 usual…
Properties of an interplanetary shock observed at 0.07 and 0.7 Astronomical Units by Parker Solar Probe and Solar Orbiter
D. Trotta, A. Larosa, G. Nicolaou +23
The Parker Solar Probe (PSP) and Solar Orbiter (SolO) missions opened a new observational window in the inner heliosphere, which is finally accessible to direct measurements. On Se…
The Automatic Identification and Tracking of Coronal Flux Ropes -- Part II: New Mathematical Morphology-based Flux Rope Extraction Method and Deflection Analysis
Andreas Wagner, Slava Bourgeois, Emilia K. J. Kilpua +9
We present a magnetic flux rope (FR) extraction tool for solar coronal magnetic field modelling data, which builds upon the methodology from Wagner et al. (2023). We apply the sche…
Studying the spheromak rotation in data-constrained CME modelling with EUHFORIA and assessing its effect on the Bz prediction
Ranadeep Sarkar, Jens Pomoell, Emilia Kilpua +4
A key challenge in space weather forecasting is accurately predicting the magnetic field topology of interplanetary coronal mass ejections (ICMEs), specifically the north-south mag…
Spatially resolved radio signatures of electron beams in a coronal shock
Peijin Zhang, Diana Morosan, Anshu Kumari +1
Context. Type II radio bursts are solar radio burst associated with coronal shocks. Type II bursts usually exhibit fine structures in dynamic spectra that represent signatures of a…
