Topological structure of the magnetic solar corona

, 2007
The solar corona is a highly complex and active plasma environment, containing many exotic phenomena such as solar flares, coronal mass ejections, prominences, coronal loops, and bright points.

Parallel and perpendicular cascades in solar wind turbulence

, 2005
MHD-scale fluctuations in the velocity, magnetic, and density fields of the solar wind are routinely observed. The evolution of these fluctuations, as they are transported radially outwards by the solar wind, is believed to involve both wave and ...

Temporal Evolution of Sunspot Groups and Increase in the Open Flux during Solar Maximum in Cycle 24

The Astrophysical Journal
The evolution of the global solar magnetic field directly impacts the interplanetary magnetic field (IMF). During the solar maximum of Cycle 24, the monthly averaged IMF strength doubled over five Carrington rotations (CRs) in late 2014.

Development and application of a global magnetic field evolution model for the solar corona

, 2009
Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

Solar magnetic field reversal as seen at Ulysses

, 2003
The rapid motion of the Ulysses spacecraft from high southern to high northern latitudes in 2000–2001 provided an excellent opportunity to make inferences regarding the solar magnetic dipole's behaviour around solar maximum.

Evolutionary Dynamics of Counterhelical Magnetic Flux Ropes

The Astrophysical Journal
Upon interaction, a pair of magnetic flux ropes can merge to form a new pair, each consisting of opposite helicity along their axis. Magnetic helicity along such new structures may annihilate and release the energy of the azimuthal magnetic field.

Comparison of Solar Wind Current Sheets in the Inner Heliosphere

The Astrophysical Journal
The solar wind is filled with intense current sheets (magnetic field discontinuities) that host multiple instabilities and may undergo magnetic reconnection, a basic process for plasma heating and charged particle acceleration.

SOLAR ERUPTION ON 4 JANUARY 2011: CASE STUDY FOR SPACE EARLY WARNING

, 2011
We perform intuitive analysis for solar eruption on 4 January 2011. Since we do not have magnetic observational data from the eruption, we perform first order calculation and expands it as interplanetary total effect of energy propagation by retro ...

Scale and Time Dependence of Alfvénicity in the Solar Wind as Observed by the Parker Solar Probe

The Astrophysical Journal
Alfvénicity is a well-known property, common in the solar wind, characterized by a high correlation between magnetic and velocity fluctuations. Data from the Parker Solar Probe (PSP) enable the study of this property closer to the Sun than ever before ...
