Convective blueshifts in the solar atmosphere, I. Absolute measurements with LARS of the spectral lines at 6302 Å
Johannes Löhner-Böttcher, Wolfgang Schmidt, Franziska Stief +2
The solar convection manifests as granulation and intergranulation at the solar surface. In the photosphere, convective motions induce differential Doppler shifts to spectral lines…
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…
Magneto-optical effects in the scattering polarization wings of the Ca I resonance line at 4227 angstroms
E. Alsina Ballester, L. Belluzzi, J. Trujillo Bueno
The linear polarization pattern produced by scattering processes in the Ca I resonance line at 4227 angstroms is a valuable observable for probing the solar atmosphere. Via the Han…
Maximum Entropy Limit of Small-scale Magnetic Field Fluctuations in the Quiet Sun
A. Y. Gorobets, S. V. Berdyugina, T. L. Riethmüller +12
The observed magnetic field on the solar surface is characterized by a very complex spatial and temporal behavior. Although feature-tracking algorithms have allowed us to deepen ou…
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…
The Direct Effect of Toroidal Magnetic Fields on Stellar Oscillations: An Analytical Expression for the General Matrix Element
René Kiefer, Ariane Schad, Markus Roth
Where is the solar dynamo located and what is its modus operandi? These are still open questions in solar physics. Helio- and asteroseismology can help answer them by enabling us t…
