ESTIMATE OF CORONAL MAGNETIC FIELD STRENGTH USING PLASMOID ACCELERATION MEASUREMENT

A New Precise Measurement of the Coronal Magnetic Field Strength

Magnetism dominates the structure and dynamics of the solar corona. Current theories suggest that it may also be responsible for coronal heating. Despite the importance of the magnetic field in the physics of the corona and despite the tremendous progress made recently in the remote sensing of solar magnetic fields, reliable measurements of the coronal magnetic field strength and orientation do...

Reconstruction of Solar Coronal Linear Force-Free Magnetic Field

Estimate of the magnetic field strength in heavy-ion collisions

One of the most exciting signals of the deconfinement and the chiral phase transitions in heavy-ion collisions, the chiral magnetic effect, suggested in Ref. [1], predicts the preferential emission of charged particles along the direction of angular momentum in the case of the noncentral heavy-ion collisions due to the presence of nonzero chirality. This effect is because the strong magnetic fi...

Coronal Magnetic Field Measurements

A long-standing solar problem has been to measure the coronal magnetic field. We believe it determines the coronal structure and dynamics from the upper chromosphere out into the heliospheric environment. It is only recently that Zeeman splitting observations of infrared coronal emission lines have been successfully used to deduce the coronal magnetic flux density. Here we extend this technique...

Coronal magnetic field measurement using loop oscillations observed by Hinode/EIS

We report the first spectroscopic detection of a kink MHD oscillation of a solar coronal structure by the Extreme-Ultraviolet Imaging Spectrometer (EIS) on the Japanese Hinode satellite. The detected oscillation has an amplitude of 1 km s−1 in the Doppler shift of the FeXII 195 Å spectral line (1.3 MK), and a period of 296 s. The unique combination of EIS’s spectroscopic and imaging abilities e...
