Features of formation of small-scale wave disturbances during a sudden magnetospheric compression

Solar-Terrestrial Physics, 2017
Quasi-periodic changes of the geomagnetic field and plasma parameters in the range of Pc 5 pulsations, which occurred immediately after the interaction of interplanetary shock (IPS) with Earth’s magnetosphere in the event of April 24, 2009 at 00:53 UT ...

Interplanetary stream interfaces [PDF]

At l AU there is a distinct boundary (the stream interface) at the leading edge of a stream in the solar wind, characterized by an abrupt drop in density, a similar increase in temperature and a small increase in speed.

Testing the Empirical Shock Arrival Model using Quadrature Observations

, 2013
The empirical shock arrival (ESA) model was developed based on quadrature data from Helios (in-situ) and P-78 (remote-sensing) to predict the Sun-Earth travel time of coronal mass ejections (CMEs) [Gopalswamy et al. 2005a].

Modelling large solar proton events with the shock-and-particle model

Journal of Space Weather and Space Climate, 2015
We have developed a new version of a model that combines a two-dimensional Sun-to-Earth magnetohydrodynamic (MHD) simulation of the propagation of a CME-driven shock and a simulation of the transport of particles along the interplanetary magnetic field ...

Effect of interplanetary shock waves on turbulence parameters [PDF]

Annales Geophysicae
We perform an extensive statistical investigation of how interplanetary fast forward shocks affect certain turbulence parameters, namely, the normalised cross-helicity, σc; residual energy, σr; and magnetic helicity, σm.

Spectral Evolution of Pickup Ions across Interplanetary Shocks in the Outer Heliosphere: Observational Constraints and Transport Simulations

The Astrophysical Journal Letters
Pickup ions (PUIs) often experience acceleration and heating as they traverse interplanetary shocks, leading to the formation of a distinct suprathermal tail in their energy spectra downstream of the shock.

Connecting speeds, directions and arrival times of 22 coronal mass ejections from the Sun to 1 AU

, 2014
Forecasting the in situ properties of coronal mass ejections (CMEs) from remote images is expected to strongly enhance predictions of space weather, and is of general interest for studying the interaction of CMEs with planetary environments. We study the

Evolution of Electron Acceleration by Corotating Interaction Region Shocks at 1 au

The Astrophysical Journal Letters
We present the first observations of in situ electron acceleration at corotating interaction region (CIR) shocks near 1 au, utilizing measurements from Wind and Magnetospheric Multiscale (MMS) mission in the interplanetary medium. As the forward (reverse)

Iron charge states observed in the solar wind [PDF]

, 1983
Solar wind measurements from the ULECA sensor of the Max-Planck-Institut/University of Maryland experiment on ISEE-3 are reported. The low energy section of approx the ULECA sensor selects particles by their energy per charge (over the range 3.6 keV/Q to
