Three-lobed near-infrared Stokes V profiles in the quiet Sun
Christoph Kiess, Juan Manuel Borrero, Wolfgang Schmidt
We investigate a region of the quiet solar photosphere exhibiting three-lobed Stokes V profiles in the Fe I spectral line at 15648 Angstroem. The data were acquired with the GRIS s…
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…
Magnetic fields of opposite polarity in sunspot penumbrae
M. Franz, M. Collados, C. Bethge +25
Context. A significant part of the penumbral magnetic field returns below the surface in the very deep photosphere. For lines in the visible, a large portion of this return field c…
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…
Properties of sunspot umbrae observed in Cycle 24
Christoph Kiess, Reza Rezaei, Wolfgang Schmidt
We analyzed the size, intensity, and magnetic field strength of sunspot umbrae to compare the present cycle 24 with the previous one. We used data of the Helioseismic and Magnetic…
