Superstrong magnetic fields in sunspot bipolar light bridges
J. S. Castellanos Durán, A. Korpi-Lagg, S. K. Solanki +2
Recent solar observations of bipolar light bridges (BLBs) in sunspots have, in a few individual cases, revealed magnetic fields up to 8.2 kG, which is at least twice as strong as t…
How rare are counter Evershed flows?
J. Sebastián Castellanos Durán, Andreas Lagg, Sami K. Solanki
One of the main characteristics of the penumbra of sunspots is the radially outward-directed Evershed flow. Only recently have penumbral regions been reported with similar characte…
The Statistical Relationship between White-light Emission and Photospheric Magnetic Field Changes in Flares
J. S. Castellanos Durán, L. Kleint
Continuum emission, also called white-light emission (WLE), and permanent changes of the magnetic field () are often observed during solar flares. But their relati…
Fast downflows in a chromospheric filament
K. Sowmya, A. Lagg, S. K. Solanki +1
An active region filament in the upper chromosphere is studied using spectropolarimetric data in He I 10830 A from the GREGOR telescope. A Milne-Eddingon based inversion of the Unn…
A Statistical Study of Photospheric Magnetic Field Changes During 75 Solar Flares
J. S. Castellanos Durán, L. Kleint, B. Calvo-Mozo
Abrupt and permanent changes of photospheric magnetic fields have been observed during solar flares. The changes seem to be linked to the reconfiguration of magnetic fields, but th…
