Planar Magnetic Structures Downstream of Coronal Mass Ejection–driven Shocks in the Inner Heliosphere

The Astrophysical Journal, 2023
Planar magnetic structures (PMSs), characterized by interplanetary magnetic field vectors remaining parallel to a specific plane, are commonly observed in the solar wind, especially in the sheath region of interplanetary coronal mass ejections (ICMEs ...

Space-based tests of gravity with laser ranging [PDF]

, 2006
Existing capabilities in laser ranging, optical interferometry and metrology, in combination with precision frequency standards, atom-based quantum sensors, and drag-free technologies, are critical for the space-based tests of fundamental physics; as a ...

From the Sun’s atmosphere to the Earth’s atmosphere: an overview of scientific models available for space weather developments [PDF]

Annales Geophysicae, 2002
Space weather aims at setting operational numerical tools in order to nowcast, forecast and quantify the solar activity events, the magnetosphere, ionosphere and thermosphere responses and the consequences on our technological societies.

Betatron Acceleration of Suprathermal Electrons within a Small-scale Flux Rope in the Solar Wind

The Astrophysical Journal Letters, 2023
A growing body of evidence from observations, theories, and simulations indicates that particles can be effectively accelerated in solar wind regions filled with dynamic small-scale flux ropes (FRs).

Physical Properties of the Interplanetary Dust [PDF]

International Astronomical Union Colloquium, 1971
The interplanetary dust may be composed of cometary material, interstellar grains, debris from asteroidal collisions, primordial material formed by direct condensation, or contributions from all of these sources. Before we can determine the origin of the dust, we need to know its physical nature, spatial distribution, and the dynamical forces that act ...

The active processes in comets as indicators of physical conditions in the interplanetary space [PDF]

Astronomical School’s Report, 2000
The results of researches of cometary flash activity obtained by authors are generalized. On the basis of this results the new evidences of relation between comets' light curves and level of solar activity are enunciated. A relation of cometary flash activity with heliocentric distances discovered by authors is permit the light curves of comets will be

Modelling interplanetary CMEs using magnetohydrodynamic simulations [PDF]

Annales Geophysicae, 2002
The dynamics of Interplanetary Coronal Mass Ejections (ICMEs) are discussed from the viewpoint of numerical modelling. Hydrodynamic models are shown to give a good zero-order picture of the plasma properties of ICMEs, but they cannot model the ...

Observations of interplanetary scintillation during the 1998 Whole Sun Month: a comparison between EISCAT, ORT and Nagoya data [PDF]

Annales Geophysicae, 2000
Observations of interplanetary scintillation (IPS) allow accurate solar wind velocity measurements to be made at all heliographic latitudes and at a range of distances from the Sun.

Advancing Tests of Relativistic Gravity via Laser Ranging to Phobos [PDF]

, 2010
Phobos Laser Ranging (PLR) is a concept for a space mission designed to advance tests of relativistic gravity in the solar system. PLR's primary objective is to measure the curvature of space around the Sun, represented by the Eddington parameter $\gamma$
