Coronal Magnetometry with EUV Permitted Lines
Nataliia G. Shchukina, Javier Trujillo Bueno, Supriya Hebbur Dayananda +2
A major challenge in solar physics is to obtain empirical information on the magnetic field of the million-degree plasma of the solar corona. To this end, we need observables of th…
The dependence of the gradients of oxygen and nitrogen-to-oxygen on stellar age in MaNGA galaxies
I. A. Zinchenko, J. M. Vilchez, E. Perez-Montero +3
We derive the oxygen abundance (O/H), the nitrogen-to-oxygen (N/O) abundance ratio, and their corresponding radial gradients for a sample of 1431 galaxies from MaNGA DR15 survey us…
New light on an old problem of the cores of solar resonance lines
Philip Judge, Lucia Kleint, Jorrit Leenaarts +2
We re-examine a 50+ year-old problem of deep central reversals predicted for strong solar spectral lines, in contrast to the smaller reversals seen in observations. We examine data…
Three-dimensional modeling of chromospheric spectral lines in a simulated active region
Johan P. Bjørgen, Jorrit Leenaarts, Matthias Rempel +4
Because of the complex physics that governs the formation of chromospheric lines, interpretation of solar chromospheric observations is difficult. The origin and characteristics of…
Three-dimensional modeling of the Ca II H&K lines in the solar atmosphere
Johan P. Bjørgen, Andrii V. Sukhorukov, Jorrit Leenaarts +4
CHROMIS, a new imaging spectrometer at the Swedish 1-m Solar Telescope (SST), can observe the chromosphere in the H and K lines of Ca II at high spatial and spectral resolution. Ac…
Comparison of Solar Fine Structure Observed Simultaneously in Ly-α and Mg II h
D. J. Schmit, A. V. Sukhorukov, B. De Pontieu +9
The Chromospheric Lyman Alpha Spectropolarimeter (CLASP) observed the Sun in H I Lyman-α during a suborbital rocket flight on September 3, 2015. The Interface Region Imaging Telesc…
Partial redistribution in 3D non-LTE radiative transfer in solar atmosphere models
Andrii V. Sukhorukov, Jorrit Leenaarts
Resonance spectral lines such as H I Ly α, Mg II h&k, and Ca II H&K that form in the solar chromosphere are influenced by the effects of 3D radiative transfer as well as partial re…
