Evidence for the solar wind in lunar magmas: A study of slowly cooled samples of the Apollo 12 olivine basalt suite
hydrogen isotopes melt inclusions mare basalts SIMS lunar olivine
2017/4/10
While it is now recognized that the Moon has indigenous water and volatiles, their total abundances are unclear, with
current literature estimates ranging from nearly absent to Earth-like levels. Sim...
On the relation between ionospheric winter anomalies and solar wind
Ionospheric winter anomalies solar wind
2015/9/28
There are two different winter anomalies. A small one that appears in connection with ionization at relatively low latitudes in the bottom of the D-region of the ionosphere. There, the electron densit...
A dynamic system to forecast ionospheric storm disturbances based on solar wind conditions
inospheric forecasting ionospheric modelling ionospheric storms
2015/9/10
For the reliable performance of technologically advanced radio communications systems under geomagnetically
disturbed conditions, the forecast and modelling of the ionospheric response during storms ...
Depth profiling analysis of solar wind helium collected in diamond-like carbon film from Genesis
solar wind depth profile helium NASA Genesis mission post-ionization
2017/4/10
The distribution of solar-wind ions in Genesis mission collectors, as determined by depth profiling analysis, constrains
the physics of ion-solid interactions involving the solar wind. Thus, they pro...
Alfvén Waves in the Solar Wind
Alfvé, n wave Solar wind Rotational Discontinuity Tangential Discontinuity Solar wind structures
2013/10/3
Alfvén waves are found to be ubiquitous in the solar wind. Recent progress in observational studies of the waves is reviewed to formulate a microscopic picture for the Alfvénic fluctuations. The main ...
Changes in Sea-Level Pressure over South Korea Associated with High-Speed Solar Wind Events
solar-terrestrial weather sea-level pressure solar wind
2011/9/30
We explore a possibility that the daily sea-level pressure (SLP) over South Korea responds to the high-speed solar wind event. This is of interest in two aspects: First, if there is a statistical asso...

Abstract: We explore a possibility that the daily sea-level pressure (SLP) over South Korea responds to the high-speed solar wind event. This is of interest in two aspects: First, if there is a statis...
Apparent temperature anisotropies due to wave activity in the solar wind
Solar wind plasma — Wave–particle interactions—Waves in plasma.
2011/9/8
The fast solar wind is a collisionless plasma permeated by plasma waves on many different scales. A plasma wave represents the natural interplay between the periodic changes of the electromagnetic fie...
The higher order statistics of magnetic field magnitude fluctuations in the fast quiet solar wind are quantified systematically scale-by-scale for the first time. We find a single global non-Gaussian ...
The Effect of Magnetic Turbulence Energy Spectra and Pickup Ions on the Heating of the Solar Wind
Pickup ions, Solar wind heating, MHD turbulence, Wave-particle interaction
2011/9/9
In recent years, a phenomenological solar wind heating model based on a turbulent energy cascade prescribed by the Kolmogorov theory has produced reasonably good agreement with observations on proton ...
Kolmogorov versus Iroshnikov-Kraichnan spectra: Consequences for ion heating in the solar wind
Kolmogorov Iroshnikov-Kraichnan spectra the solar wind
2011/9/9
Whether the phenomenology governing MHD turbulence is Kolmogorov or Iroshnikov-Kraichnan (IK) remains an open question, theoretically as well as observationally. The ion heating profile observed in th...
Ultraviolet Coronagraph Spectroscopy: A Key Capability for Understanding the Physics of Solar Wind Acceleration
Ultraviolet Coronagraph Spectroscopy Physics of Solar Wind Acceleration
2010/11/15
Understanding the physical processes responsible for accelerating the solar wind requires detailed measurements of the collisionless plasma in the extended solar corona. Some key clues about these pro...
We analyze a large, complex equatorial coronal hole (ECH) and its immediate surroundings with a focus on the roots of the fast solar wind. We start by demonstrating that our ECH is indeed a source of...
Solar Wind Drag and the Kinematics of Interplanetary Coronal Mass Ejections
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Coronal mass ejections (CMEs) are large-scale ejections of plasma and magnetic field from the solar corona, which propagate through interplanetary space at velocities of $\sim$100--2500~km~s$^{-1}$.
