Magnetic Energy Storage and Current Density Distributions for Different Force-Free Models
Magnetic fi elds Corona - Active Regions Structure - Electric Cur- rents Current Sheets
2011/10/10
The change in the magnetic configuration due to the increase/decrease of electric current for different force-free models (potential, linear and nonlinear force-free fields) has never been studied in ...
Obliquely rotating pulsars: current screening
Obliquely rotating pulsars current screening
2011/9/26
Pulsar electrodynamics has been built up by taking ingredients from two models, the vacuum-dipole model, which ignores the magnetosphere but includes the inductive electric field due to the obliquely ...

Cosmic rays: current status, historical context
Cosmic rays current status historical context
2011/1/13
The ISVHECRI conference series emphasizes the connection between high energy physics and cosmic ray physics--the study of elementary particles and nuclei from accelerators in the lab and from space. I...
Characters of current type Ia supernovae data based on evolving dark energy models
dark energy theory supernova type Ia - standard candles cosmological param-eters from CMBR
2010/11/11
We study characters of recent type Ia supernova (SNIa) data using evolving dark energy models with changing equation of state parameter w. We consider sudden-jump approximation of w for some chosen re...
Vector Magnetic Fields and Current Helicities in Coronal Holes and Quiet Regions
Sun activity — Sun magnetic fields — Sun photosphere
2010/11/10
In the solar photosphere, many properties of coronal holes (CHs) are notknown, especially vector magnetic fields. Using observations from Hinode, we investigate vector magnetic fields, current densiti...
Status and Strategies of Current LUNASKA Lunar Cherenkov Observations with the Parkes Radio Telescope
High Energy Astrophysical Phenomena (astro-ph.HE) Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/28
LUNASKA (Lunar UHE Neutrino Astrophysics with the Square Kilometre Array) is an ongoing project conducting lunar Cherenkov observations in order to develop techniques for detecting neutrinos with the ...
Comparison of current models for Hot Jupiters to the sample of transiting exoplanets
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/24
A growing number (over 100!) of extra-solar planets (ESPs) have been discovered by transit photometry, and these systems are important because the transit strongly constrains their orbital inclination...
Cosmic-ray current driven turbulence in shocks with efficient particle acceleration: the oblique, long-wavelength mode instability
High Energy Astrophysical Phenomena (astro-ph.HE) Plasma Physics (physics.plasm-ph)
2010/12/23
In order for diffusive shock acceleration (DSA) to accelerate particles to high energies, the energetic particles must be able to interact with magnetic turbulence over a broad wavelength range.
Evidence for a current sheet forming in the wake of a Coronal Mass Ejection from multi-viewpoint coronagraph observations
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Ray-like features observed by coronagraphs in the wake of Coronal Mass Ejections (CMEs) are sometimes interpreted as the white light counterparts of current sheets (CSs) produced by the eruption.
The Solar Wind: Our Current Understanding and How We Got Here
Solar wind coronal holes solar corona cyclotron resonance MHD waves
2010/9/16
In the original theory for the solar wind, the electron pressure gradient was the principal accelerating force. This was soon recognized to be insufficient to drive the high-speed streams. Subsequentl...
Models of Solar Irradiance Variations: Current Status
Sun activity faculae plages magnetic fields solar irradiance solar-terrestrial relations sunspots
2010/9/15
Regular monitoring of solar irradiance has been carried out since 1978 to show that solar total and spectral irradiance varies at different time scales. Whereas variations on time scales of minutes to...
Probing modifications of General Relativity using current cosmological observations
General Relativity integrated Sachs-Wolfe weak lensing
2010/3/9
We test General Relativity (GR) using current cosmological data: the cosmic microwave background (CMB) from WMAP5 (Komatsu et al. 2009), the integrated Sachs-Wolfe (ISW) effect from the cross-correla...
The Current Status of Binary Black Hole Simulations in Numerical Relativity
Black Hole Simulations Numerical Relati
2010/3/18
Since the breakthroughs in 2005 which have led to long term stable solutions of the binary black hole problem in numerical relativity, much progress has been made. I present here a short summary of th...
