The European Solar Telescope
C. Quintero Noda, R. Schlichenmaier, L. R. Bellot Rubio +14
The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design…
Highly sensitive search for magnetic fields in white dwarfs using broad-band circular polarimetry
Andrei V. Berdyugin, Vilppu Piirola, Stefano Bagnulo +2
Circular polarisation measurements of white dwarfs of various ages and spectral types are useful to understand the origin and evolution of the magnetic field in degenerate stars. I…
The First Post-Kepler Brightness Dips of KIC 8462852
Tabetha S. Boyajian, Roi Alonso, Alex Ammerman +203
We present a photometric detection of the first brightness dips of the unique variable star KIC 8462852 since the end of the Kepler space mission in 2013 May. Our regular photometr…
Quiet-Sun intensity contrasts in the near ultraviolet
Johann Hirzberger, Alex Feller, Tino L. Riethmüller +14
We present high-resolution images of the Sun in the near ultraviolet spectral range between 214 nm and 397 nm as obtained from the first science flight of the 1-m Sunrise balloon-b…
GJ 841B - The Second DQ White Dwarf with Polarized CH Molecular Bands
Tommi Vornanen, Svetlana Berdyugina, Andrei Berdyugin +1
We report a discovery of the circularly polarized CH and molecular bands in the spectrum of the DQ white dwarf GJ 841B. This is only the second such obje…
Turbulent magnetic fields in the quiet Sun: A search for cyclic variations
L. Kleint, S. V. Berdyugina, A. I. Shapiro +1
Turbulent magnetic fields fill most of the volume of the solar atmosphere. However, their spatial and temporal variations are still unknown. Since 2007, during the current solar mi…
