Magnetic Topology of Active Regions and Coronal Holes: Implications for Coronal Outflows and the Solar Wind
(Springer, 2012-11)
During 2-18 January 2008 a pair of low-latitude opposite-polarity coronal holes (CHs) were observed on the Sun with two active regions (ARs) and the heliospheric plasma sheet located between them. We use the Hinode/EUV ...
Active-region twist derived from magnetic tongues and linear force-free extrapolations
(Springer, 2015-12)
The main aim of this study is to compare the amount of twist present in emerging active regions (ARs) from photospheric and coronal data. We use linear force-free field models of the observed coronal structure of ARs to ...
How Can Active Region Plasma Escape into the Solar Wind from Below a Closed Helmet Streamer?
(Springer, 2014-11)
Recent studies show that active-region (AR) upflowing plasma, ob- served by the EUV-Imaging Spectrometer (EIS), onboard Hinode, can gain access to open field-lines and be released into the solar wind (SW) via magnetic- ...
The Magnetic Structure of Coronal Loops Observed by TRACE
(IOP Publishing, 2006-12)
Previous studies have found that coronal loops have a nearly uniform thickness, which seems to disagree with the characteristic expansion of active region magnetic fields. This is one of the most intriguing enigmas in solar ...
Superconducting 3D-sample with general boundary conditions in a tilted magnetic field
(2019-03-15)
We consider a mesoscopic superconducting three-dimensional cube immersed in a tilted magnetic field H oriented along an angle θ with respect to the z-axis, in the xz plane. The sample is in contact with a metallic material ...
Influence of the deGennes extrapolation parameter on the resistive state of a superconducting strip
(2018-01-30)
We studied the resistive state of a mesoscopic superconducting strip (bridge) at zero external applied magnetic field under a transport electric current, Ja, subjected to different types of boundary conditions. The current ...
Measuring the magnetic field of a trans-equatorial loop system using coronal seismology
(EDP Sciences, 2017-07)
Context. EIT waves are freely-propagating global pulses in the low corona which are strongly associated with the initial evolution of coronal mass ejections (CMEs). They are thought to be large-Amplitude, fast-mode ...
Anticipating hyperthermic efficiency of magnetic colloids using a semi-empirical model: A tool to help medical decisions
(Royal Society of Chemistry, 2017-01)
Magnetic hyperthermia, a modality that uses radio frequency heating assisted with single-domain magnetic nanoparticles, is becoming established as a powerful oncological therapy. Much improvement in nanomaterials development, ...
