Spectropolarimetry of the Solar Mg II h and k Lines
We report on spectropolarimetric observations across the Mg II h and k lines at 2800 Å made by the Ultraviolet Spectrometer and Polarimeter on board the Solar...
The Chromosphere Underneath a Coronal Bright Point
Coronal bright points (CBPs) are sets of small-scale coronal loops, connecting opposite magnetic polarities, primarily characterized by their enhanced extreme...
The Circular Polarization of the Mn 1 Resonance Lines around 280 nm for Exploring Chromospheric Magnetism
We study the circular polarization of the Mn I resonance lines at 279.56, 279.91, and 280.19 nm (hereafter, UV multiplet) by means of radiative transfer...
The COSMO Chromosphere and Prominence Magnetometer
The Chromosphere and Prominence Magnetometer (ChroMag) is a synoptic instrument with the goal of quantifying the intertwined dynamics and magnetism of the solar...
The GREGOR Fabry-Pérot Interferometer: Status, prospects, and scientific aims
The GREGOR Fabry-Pérot Interferometer (GFPI) is one of the first-light post-focus instruments for the German 1.5-meter GREGOR solar telescope at the...
The loopy Sun: resolving the small-scale solar magnetism
Solar magnetism may look deceptively boring (a rather common star with relatively low activity). As it turns out, even the most quiet areas of the Sun (away...
The Magnetic Sensitivity of the (250-278 nm) Fe II Polarization Spectrum
This paper presents a theoretical investigation of the polarization and magnetic sensitivity of the near-ultraviolet (near-UV) solar spectral lines of Fe II...
The Plasma β in Quiet Sun Regions: Multi-instrument View
A joint campaign of several spaceborne and ground-based observatories, such as the GREGOR solar telescope, the Extreme-ultraviolet Imaging Spectrometer (EIS)...
The Potential of the Wavelength-integrated Scattering Polarization of the Hydrogen Lyα Line for Probing the Solar Chromosphere
The intensity and the linear scattering polarization profiles of the hydrogen Lyα line encode valuable information on the thermodynamic and magnetic structure...
