A set of seismic observations which all sample the same structure in the same way should have zero variance. This is naturally the case if all sources are in the same place, and the data are recorded ...

Measurement requirements for a near-Earth asteroid impact mitigation demonstration mission
Near-Earth Asteroids Impact Mitigation Spacecraft Missions
2011/8/17
Abstract: A concept for an Impact Mitigation Preparation Mission, called Don Quijote, is to send two spacecraft to a Near-Earth Asteroid (NEA): an Orbiter and an Impactor. The Impactor collides with t...
Accurate Measurement in the Field of the Earth of the General-Relativistic Precession of the LAGEOS II Pericenter and New Constraints on Non-Newtonian Gravity
General-Relativistic Pericenter Constraints on Non-Newtonian Gravity
2011/9/14
The pericenter shift of a binary system represents a suitable observable to test for possible deviations from the Newtonian inverse–square law in favor of new weak interactions between macroscopic obj...
Nonlinear wave-particle interaction upstream from the Earth's bow shock
Nonlinear wave-particle interaction upstream Earth's bow shock
2009/11/13
Well-defined ring-like backstreaming ion distributions have been recently reported from observations made by the 3DP/PESA-High analyzer onboard the WIND spacecraft in the Earth's foreshock at large di...
A theory of the Earth's magnetic field and of sunspots,based on a self-excited dynamo incorporating the Hall effect
Earth's magnetic field self-excited dynamo Hall effect
2009/11/12
A new viewpoint on the generation and maintenance of the Earth's magnetic field is put forward, which integrates self-exciting dynamo theory with the possibility of energy coupling along orthogonal ax...
Jump conditions for pressure anisotropy and comparison with the Earth's bow shock
Jump conditions pressure anisotropy Earth's bow shock
2009/11/12
Taking into account the pressure anisotropy in the solar wind, we study the magnetic field and plasma parameters downstream of a fast shock, as functions of upstream parameters and downstream pressure...
Calculation of the parameter deflection in a new theory of the Earth’s magnetic field
parameter deflection new theory Earth’s magnetic field
2009/11/12
In a recent paper on the theory of the Earth's magnetic field and key features of Sunspot activity (de Paor, 2001), a central role in the calculation of secular variations of the geomagnetic field was...
In a recent paper de Paor put forward a new theory of the Earth's magnetic field that depended on the Hall effect as an energy transfer mechanism. The purpose of this paper is to demonstrate that the ...
Clarification of the Hall effect as an energy transfer mechanism in a theory of the Earth’s magnetic field and sunspots
Hall effect energy transfer mechanism Earth’s magnetic field and sunspots
2009/11/12
Clarification is offered of the energy transfer role played by the Hall effect in a recent paper: de Paor, A., A theory of the Earth's magnetic field and of sunspots, based on a self-excited dynamo in...
Large amplitude solitary waves in and near the Earth’s magnetosphere,magnetopause and bow shock:Polar and Cluster observations
Large amplitude solitary waves Earth’s magnetosphere magnetopause bow shock
2009/11/11
Solitary waves with large electric fields (up to 100's of mV/m) have been observed throughout the magnetosphere and in the bow shock. We discuss observations by Polar at high altitudes ( ~ 4-8 RE ), d...
