Earth-affecting solar transients: a review of progresses in solar cycle 24
- PhysicsProgress in Earth and Planetary Science
- 2021
The unprecedented multi-viewpoint observations of the Sun from space, enabled by STEREO Ahead/Behind spacecraft in combination with a suite of observatories along the Sun-Earth lines, have provided much more accurate and global measurements of the size, speed, propagation direction, and morphology of CMEs in both 3D and over a large volume in the heliosphere.
Flux Ropes as Singularities of the Vector Potential
- Physics
- 2015
A flux rope is a domain where a twisted magnetic field [B] is concentrated; it can be described as the core of a singularity of the outer field or the outer vector potential [A] (Kleman and Robbins…
Magnetic field line lengths inside interplanetary magnetic flux ropes
- Physics
- 2015
We report on the detailed and systematic study of field line twist and length distributions within magnetic flux ropes embedded in interplanetary coronal mass ejections (ICMEs). The Grad‐Shafranov…
Access of cosmic rays to an ICME from external field lines
- PhysicsProceedings of 37th International Cosmic Ray Conference — PoS(ICRC2021)
- 2021
Interplanetary coronal mass ejections (ICMEs) cause decreases, so-called Forbush decreases, in the cosmic ray (CR) intensities. FDs are seen as up to 25% decreases in neutron monitor counts at Earth,…
Magnetic flux ropes in the solar corona: structure and evolution toward eruption
- Physics
- 2020
Magnetic flux ropes are characterized by coherently twisted magnetic field lines, which are ubiquitous in magnetized plasmas. As the core structure of various eruptive phenomena in the solar…
Effects of twist on the evolution of knotted magnetic flux tubes
- Physics, MathematicsJournal of Fluid Mechanics
- 2020
We develop a general method for constructing knotted flux tubes with finite thickness, arbitrary shape and tunable twist. The central axis of the knotted tube is specified by a smooth and…
Re-analysis of Lepping’s Fitting Method for Magnetic Clouds: Lundquist Fit Reloaded
- Physics
- 2019
Magnetic clouds (MCs) are a subset of ejecta, launched from the Sun as coronal mass ejections. The coherent rotation of the magnetic field vector observed in MCs leads to envision MCs as formed by…
