Determining the acceleration regions of in situ electrons using remote radio and X-ray observations
D. E. Morosan, N. Dresing, C. Palmroos +13
Solar energetic particles in the heliosphere are produced by flaring processes on the Sun or shocks driven by coronal mass ejections. These particles are regularly detected remotel…
The effect of data-driving and relaxation model on magnetic flux rope evolution and stability
Andreas Wagner, Daniel J. Price, Slava Bourgeois +7
We investigate the effect of data-driving on flux rope eruptivity in magnetic field simulations by analysing fully data-driven modelling results of active region (AR) 12473 and AR1…
Direct Measurements of Synchrotron-Emitting Electrons at Near-Sun Shocks
I. C. Jebaraj, O. V. Agapitov, M. Gedalin +22
In this study, we present the first-ever direct measurements of synchrotron-emitting heliospheric traveling shocks, intercepted by the Parker Solar Probe (PSP) during its close enc…
Validation of EUHFORIA cone and spheromak Coronal Mass Ejection Models
L. Rodriguez, D. Shukhobodskaia, A. Niemela +15
Aims. We present the validation results for arrival times and geomagnetic impact of Coronal Mass Ejections (CMEs), using the cone and spheromak CME models implemented in EUropean H…
Estimating the lateral speed of a fast shock driven by a coronal mass ejection at the location of solar radio emissions
S. Normo, D. E. Morosan, E. K. J. Kilpua +1
Fast coronal mass ejections (CMEs) can drive shock waves capable of accelerating electrons to high energies. These shock-accelerated electrons act as sources of electromagnetic rad…
On the Origin of the sudden Heliospheric Open Magnetic Flux Enhancement during the 2014 Pole Reversal
Stephan G. Heinemann, Mathew J. Owens, Manuela Temmer +12
Coronal holes are recognized as the primary sources of heliospheric open magnetic flux (OMF). However, a noticeable gap exists between in-situ measured OMF and that derived from re…
Validity of using Elsässer variables to study the interaction of compressible solar wind fluctuations with a coronal mass ejection
Chaitanya Prasad Sishtla, Jens Pomoell, Norbert Magyar +2
Alfvénic fluctuations, as modelled by the non-linear interactions of Alfvén waves of various scales, are seen to dominate solar wind turbulence. However, there is also a non-neglig…
Classification of Enhanced Geoeffectiveness Resulting from High-Speed Solar Wind Streams Compressing Slower Interplanetary Coronal Mass Ejections
Stephan G. Heinemann, Chaitanya Sishtla, Simon Good +2
High-speed solar wind streams (HSSs) interact with the preceding ambient solar wind to form Stream Interaction Regions (SIRs), which are a primary source of recurrent geomagnetic s…
