Brightness, distribution, and evolution of sunspot umbral dots
T. L. Riethmueller, S. K. Solanki, V. Zakharov +1
We present a 106-minute TiO (705.7nm) time series of high spatial and temporal resolution that contains thousands of umbral dots (UDs) in a mature sunspot in the active region NOAA…
Convectively driven vortex flows in the Sun
J. A. Bonet, I. Marquez, J. Sanchez Almeida +2
We have discovered small whirlpools in the Sun, with a size similar to the terrestrial hurricanes (<~0.5 Mm). The theory of solar convection predicts them, but they had remained el…
The intensity contrast of solar granulation: comparing Hinode SP results with MHD simulations
S. Danilovic, A. Gandorfer, A. Lagg +5
The contrast of granulation is an important quantity characterizing solar surface convection. We compare the intensity contrast at 630 nm, observed using the Spectro-Polarimeter (S…
Solar constraints on new couplings between electromagnetism and gravity
S. K. Solanki, O. Preuss, M. P. Haugan +6
The unification of quantum field theory and general relativity is a fundamental goal of modern physics. In many cases, theoretical efforts to achieve this goal introduce auxiliary…
