Magnetoacoustic Shocks and Spectropolarimetric Signals in He I 10830 Å
Hirdesh Kumar, Tobias Felipe, Christoph Kuckein +2
Umbral flashes are manifestations of magnetoacoustic shocks in the solar chromosphere. These phenomena are thought to influence the evolution of chromospheric umbral magnetic field…
Magnetic Flux Emergence in a Coronal Hole
J. Palacios, D. Utz, S. Hofmeister +13
A joint campaign of various space-borne and ground-based observatories, comprising the Japanese Hinode mission (HOP~338, 20\,--\,30~September 2017), the GREGOR solar telescope, and…
Capabilities of bisector analysis of the Si I 10827 A line for estimating line-of-sight velocities in the quiet Sun
S. J. González Manrique, C. Quintero Noda, C. Kuckein +2
We examine the capabilities of a fast and simple method to infer line-of-sight (LOS) velocities from observations of the photospheric Si I 10827 A line. This spectral line is routi…
Properties of the inner penumbral boundary and temporal evolution of a decaying sunspot
M. Benko, S. J. González Manrique, H. Balthasar +3
It was empirically determined that the umbra-penumbra boundaries of stable sunspots are characterized by a constant value of the vertical magnetic field. We analyzed the evolution…
