A first spectroscopic measurement of the magnetic field strength for an active region of the solar corona
Ran Si, Tomas Brage, Wenxian Li +3
For all involved in astronomy, the importance of monitoring and determining astrophysical magnetic field strengths is clear. It is also a well-known fact that the corona magnetic f…
Excitation and charge transfer in low-energy hydrogen atom collisions with neutral manganese and titanium
Jon Grumer, Paul S. Barklem
Data for inelastic processes due to hydrogen atom collisions with manganese and titanium are needed for accurate modeling of the corresponding spectra in late-type stars. In this w…
The 3D non-LTE solar nitrogen abundance from atomic lines
A. M. Amarsi, N. Grevesse, J. Grumer +3
Nitrogen is an important element in various fields of stellar and Galactic astronomy, and the solar nitrogen abundance is crucial as a yardstick for comparing different objects in…
A Novel Method to Determine Magnetic Fields in low-density Plasma e.g. Solar Flares Facilitated Through Accidental Degeneracy of Quantum States in Fe
Wenxian Li, Jon Grumer, Yang Yang +8
We propose a new method to determine magnetic fields, by using the magnetic-field induced electric dipole transition $3p^5\, ^2\mathrm{P}…
