Global maps of the magnetic field in the solar corona [PDF]

open access: yesScience, 2020
The magnetic field in the Sun's corona The solar corona is the outermost layer of the Sun's atmosphere, consisting of hot, diffuse, and highly ionized plasma. The magnetic field in this region is expected to drive many of its physical properties but has been difficult to measure with observations. Yang et al.

Improving Attitude Estimation Using Gaussian-Process-Regression-Based Magnetic Field Maps

open access: yesSensors, 2021
Magnetometers measure the local magnetic field and are present in most modern inertial measurement units (IMUs). Readings from magnetometers are used to identify Earth’s Magnetic North outdoors, but are often ignored during indoor experiments since the ...

Mapping of steady-state electric fields and convective drifts in geomagnetic fields – Part 1: Elementary models [PDF]

open access: yesAnnales Geophysicae, 2016
When studying magnetospheric convection, it is often necessary to map the steady-state electric field, measured at some point on a magnetic field line, to a magnetically conjugate point in the other hemisphere, or the equatorial plane, or at the ...

Tracing Magnetic Fields with Spectroscopic Channel Maps [PDF]

open access: yesThe Astrophysical Journal, 2018
Abstract We identify velocity channel map intensities as a new way to trace magnetic fields in turbulent media. This work makes use of both the modern theory of magnetohydrodynamic (MHD) turbulence, which predicts that magnetic eddies are aligned with the local direction of the magnetic field, and also the theory of spectral line ...
