Ca II 8542 Å brightenings induced by a solar microflare
C. Kuckein, A. Diercke, S. J. González Manrique +6
We study small-scale brightenings in Ca II 8542 Å line-core images to determine their nature and effect on localized heating and mass transfer in active regions. High-resolution 2D…
Three-dimensional structure of a sunspot light bridge
T. Felipe, M. Collados, E. Khomenko +26
Active regions are the most prominent manifestations of solar magnetic fields; their generation and dissipation are fundamental problems in solar physics. Light bridges are commonl…
Spectropolarimetric observations of an arch filament system with the GREGOR solar telescope
H. Balthasar, P. Gömöry, S. J. González Manrique +27
Arch filament systems occur in active sunspot groups, where a fibril structure connects areas of opposite magnetic polarity, in contrast to active region filaments that follow the…
Deep probing of the photospheric sunspot penumbra: no evidence for magnetic field-free gaps
J. M. Borrero, A. Asensio Ramos, M. Collados +24
Some models for the topology of the magnetic field in sunspot penumbrae predict the existence of field-free or dynamically weak-field regions in the deep Photosphere. To confirm or…
The GREGOR solar telescope on Tenerife
Wolfgang Schmidt, Oskar von der Lühe, Reiner Volkmer +14
2011 was a successful year for the GREGOR project. The telescope was finally completed in May with the installation of the 1.5-meter primary mirror. The installation of the first-l…
