Dynamics of energetic particles scattered in the solar wind : Magnetohydrodynamics and test-particle simulations
Houeibib Ahmed, Pantellini Filippo, Griton Lea
We model the transport of solar energetic particles (SEPs) in the solar wind. We propagated relativistic test particles in the field of a steady three-dimensional magnetohydrodynam…
Slow modes in the Hermean magnetosphere: effect of the solar wind hydrodynamic parameters and IMF orientation
J. Varela, F. Pantellini, M. Moncuquet
The aim of this study is to simulate the slow mode structures in the Hermean magnetosphere. We use a single fluid MHD model and a multipolar expansion of the Northward displaced He…
Effect of the interplanetary magnetic field orientation and intensity in the mass and energy deposition on the Hermean surface
J. Varela, F. Pantellini, M. Moncuquet
The aim of the present study is to simulate the interaction between the solar wind and the Hermean magnetosphere. We use the MHD code PLUTO in spherical coordinates with an axisymm…
Radio emission in Mercury magnetosphere
J. Varela, V. Reville, A. S. Brun +2
Context: Active stars possess magnetized wind that has a direct impact on planets that can lead to radio emission. Mercury is a good test case to study the effect of the solar wind…
Convective Instability Of The Solar Corona: Why The Solar Wind Blows
Joseph Lemaire
Chapman's (1957) conductive model of the solar corona is characterized by a temperature varying as r**(-2/7) with heliocentric distance r. The density distribution in this non-isot…
Half a Century of Kinetic Solar Wind Models
Joseph Lemaire
I outline the development of four generations of kinetic models, starting with Chamberlain's solar breeze exospheric model. It is shown why this first kinetic model did not give ap…
Studying the Lunar-Solar Wind Interaction with the SARA Experiment aboard the Indian Lunar Mission Chandrayaan-1
Anil Bhardwaj, Stas Barabash, M. B. Dhanya +7
The first Indian lunar mission Chandrayaan-1 was launched on 22 October 2008. The Sub-keV Atom Reflecting Analyzer (SARA) instrument onboard Chandrayaan-1 consists of an energetic…
Resonant Interactions Between Protons and Oblique Alfvén/Ion-Cyclotron Waves
Peera Pongkitiwanichakul, Benjamin D. G. Chandran, Philip A. Isenberg +1
Resonant interactions between ions and Alfvén/ion-cyclotron (A/IC) waves may play an important role in the heating and acceleration of the fast solar wind. Although such interactio…
Coronal Inflows and Giant Polar Plumes
R. Pinto, R. Grappin, J. Leorat
We present the first results of simulations of giant polar plumes and coronal flows. We use a 2.5D axisymmetric MHD numerical model of an isothermal corona and slow solar wind. A p…
Solar wind turbulent spectrum from MHD to electron scales
O. Alexandrova, J. Saur, C. Lacombe +5
Turbulent spectra of magnetic fluctuations in the free solar wind are studied from MHD to electron scales using Cluster observations. We discuss the problem of the instrumental noi…
Coupling Photosphere and Corona: Linear and Turbulent Regimes
A. Verdini, R. Grappin, M. Velli
In a recent work Grappin et al. [1] have shown that low- frequency movements can be transmitted from one footpoint to the other along a magnetic loop, thus mimicking a friction eff…
Turbulence, Energy Transfers and Reconnection in Compressible Coronal Heating Field-line Tangling Models
R. B. Dahlburg, A. F. Rappazzo, M. Velli
MHD turbulence has long been proposed as a mechanism for the heating of coronal loops in the framework of the Parker scenario for coronal heating. So far most of the studies have f…
3D Hall MHD Modeling of Solar Wind Plasma Spectra
Dastgeer Shaikh, G. P. Zank
We present fully self consistent 3D simulations of compressible Hall MHD plasma that describe spectral features relevant to the solar wind plasma. We find that a spectru…
Whistler Wave Turbulence in Solar Wind Plasma
Dastgeer Shaikh, G. P. Zank
Whistler waves are present in solar wind plasma. These waves possess characteristic turbulent fluctuations that are characterized typically by the frequency and length scales that…
Self-consistent Simulations of Plasma-Neutral in a Partially Ionized Astrophysical Turbulent Plasma
Dastgeer Shaikh, G. P. Zank
A local turbulence model is developed to study energy cascades in the heliosheath and outer heliosphere (OH) based on self-consistent two-dimensional fluid simulations. The model d…
Solar-Terrestrial Simulations of CMEs with a Realistic Initiation Mechanism: Case Study for Active Region 10069
N. Lugaz, I. I. Roussev, I. V. Sokolov +1
Most simulations of coronal mass ejections (CMEs) to date either focus on the interplanetary propagation of a giant plasma "blob" without paying too much attention to its origin an…
Upflows in the upper transition region of the quiet Sun
H. Tian, C. -Y. Tu, E. Marsch +3
We investigate the physical meaning of the prominent blue shifts of Ne VIII, which is observed to be associated with quiet-Sun network junctions (boundary intersections), through d…
Exclusion of Tiny Interstellar Dust Grains from the Heliosphere
J. D. Slavin, P. C. Frisch, J. Heerikhuisen +6
The distribution of interstellar dust grains (ISDG) observed in the Solar System depends on the nature of the interstellar medium-solar wind interaction. The charge of the grains c…
