Filigree in the Surroundings of Polar Crown and High-Latitude Filaments
A. Diercke, C. Kuckein, M. Verma +1
High-resolution observations of polar crown and high-latitude filaments are scarce. We present a unique sample of such filaments observed in high-resolution H narrow-band filter…
Classification of High-resolution Solar Hα Spectra using t-distributed Stochastic Neighbor Embedding
Meetu Verma, Gal Matijevič, Carsten Denker +7
The Hα spectral line is a well-studied absorption line revealing properties of the highly structured and dynamic solar chromosphere. Typical features with distinct spectral signatu…
Chromospheric resonances above sunspots and potential seismological applications
T. Felipe, C. Kuckein, S. J. González Manrique +2
Oscillations in sunspot umbrae exhibit remarkable differences between the photosphere and chromosphere. We evaluate two competing scenarios proposed for explaining those observatio…
Critical Science Plan for the Daniel K. Inouye Solar Telescope (DKIST)
Mark P. Rast, Nazaret Bello González, Luis Bellot Rubio +84
The Daniel K. Inouye Solar Telescope (DKIST) will revolutionize our ability to measure, understand and model the basic physical processes that control the structure and dynamics of…
Observational study of chromospheric heating by acoustic waves
V. Abbasvand, M. Sobotka, M. Švanda +9
Aims. To investigate the role of acoustic and magneto-acoustic waves in heating the solar chromosphere, observations in strong chromospheric lines are analyzed by comparing the dep…
High-resolution spectroscopy of an erupting minifilament and its impact on the nearby chromosphere
I. Kontogiannis, E. Dineva, A. Diercke +4
We study the evolution of a mini-filament eruption in a quiet region at the center of the solar disk and its impact on the ambient atmosphere. We used high-spectral resolution imag…
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…
Determining the dynamics and magnetic fields in He I 10830 Å during a solar filament eruption
C. Kuckein, S. J. González Manrique, L. Kleint +1
We investigate the dynamics and magnetic properties of the plasma, such as line-of-sight velocity (LOS), optical depth, vertical and horizontal magnetic fields, belonging to an eru…
High-resolution spectroscopy of a surge in an emerging flux region
M. Verma, C. Denker, A. Diercke +6
High-spectral resolution observations using the VTT echelle spectrograph in the chromospheric H line were obtained in the early growth phase of active region NOAA 12722. Noise-s…
Tracking downflows from the chromosphere to the photosphere in a solar arch filament system
S. J. González Manrique, C. Kuckein, A. Pastor Yabar +6
We study the dynamics of plasma along the legs of an arch filament system (AFS) from the chromosphere to the photosphere, observed with high-cadence spectroscopic data from two gro…
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…
