Dynamics of the solar granulation
Excellent spectrograms can yield observational insight in the dynamics of the solar surface not yet accessible to numerical simulations. We present results of the elaboration of a series of spectrograms taken at the center of the solar disk. Each of the spectrograms includes more than 250 granules, while the series covers a time of 12 min. Our main emphasis is to study the dynamics of the visib...
متن کاملNumerical Simulations of Oscillation Modes of the Solar Convection Zone.
We use the three-dimensional hydrodynamic code of Stein & Nordlund to realistically simulate the upper layers of the solar convection zone in order to study physical characteristics of solar oscillations. Our first result is that the properties of oscillation modes in the simulation closely match the observed properties. Recent observations from the Solar and Heliospheric Observatory (SOHO)/Mic...
متن کاملNumerical Simulations of Helicity Condensation in the Solar Corona
The helicity condensation model has been proposed by Antiochos (2013) to explain the observed smoothness of coronal loops and the observed buildup of magnetic shear at filament channels. The basic hypothesis of the model is that magnetic reconnection in the corona causes the magnetic stress injected by photospheric motions to collect only at those special locations where prominences form. In th...
متن کاملHeight variation of the solar granulation
We analyze spectral scans of narrow-band images across the Na D2 line. They were obtained from disc centre of the Sun with our Fabry-Perot interferometer (FPI) in the Vacuum Tower Telescope at the Observatorio del Teide. The FPI was set to a bandwidth of 200 mÅ FWHM and the spectral stepwidth was 100 mÅ. Our aim is to study the variation of the granulation pattern with height in the atmosphere....
متن کاملThe intensity contrast of solar granulation: comparing Hinode SP results with MHD simulations
Context. The contrast of granulation is an important quantity characterizing solar surface convection. Aims. We compare the intensity contrast at 630 nm, observed using the Spectro-Polarimeter (SP) aboard the Hinode satellite, with the 3D radiative MHD simulations of Vögler & Schüssler (2007). Methods. A synthetic image from the simulation is degraded using a theoretical point-spread function o...
