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…
Upper Chromospheric Magnetic Field of a Sunspot Penumbra: Observations of Fine Structure
J. Joshi, A. Lagg, S. K. Solanki +22
The fine-structure of magnetic field of a sunspot penumbra in the upper chromosphere is to be explored and compared to that in the photosphere. High spatial resolution spectropolar…
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…
Probing deep photospheric layers of the quiet Sun with high magnetic sensitivity
A. Lagg, S. K. Solanki, H. -P. Doerr +31
Context. Investigations of the magnetism of the quiet Sun are hindered by extremely weak polarization signals in Fraunhofer spectral lines. Photon noise, straylight, and the system…
