Dynamics of Trees of Fragmenting Granules in the Quiet Sun: Hinode/SOT Observations Compared to Numerical Simulation

J. M. Malherbe, T. Roudier, R. Stein +1

We compare horizontal velocities, vertical magnetic fields and evolution of trees of fragmenting granules (TFG, also named families of granules) derived in the quiet Sun at disk ce…

The asteroseismic surface effect from a grid of 3D convection simulations. I. Frequency shifts from convective expansion of stellar atmospheres

Regner Trampedach, Magnus J. Aarslev, Günter Houdek +4

We analyse the effect on adiabatic stellar oscillation frequencies of replacing the near-surface layers in 1D stellar structure models with averaged 3D stellar surface convection s…

Improvements to stellar structure models, based on a grid of 3D convection simulations. II. Calibrating the mixing-length formulation

Regner Trampedach, Robert F. Stein, Jørgen Christensen-Dalsgaard +2

We perform a calibration of the mixing length of convection in stellar structure models against realistic 3D radiation-coupled hydrodynamics (RHD) simulations of convection in stel…

Improvements to Stellar Structure Models, Based on a Grid of 3D Convection Simulations. I. -Relations

Regner Trampedach, Robert F. Stein, Jørgen Christensen-Dalsgaard +2

Relations between temperature, T, and optical depth, tau, are often used for describing the photospheric transition from optically thick to optically thin in stellar structure mode…

Interpreting the Helioseismic and Magnetic Imager (HMI) Multi-Height Velocity Measurements

Kaori Nagashima, Björn Löptien, Laurent Gizon +6

The Solar Dynamics Observatory/Helioseismic and Magnetic Imager (SDO/HMI) filtergrams, taken at six wavelengths around the Fe I 6173.3 Å line, contain information about the line-of…

Models of solar surface dynamics: impact on eigenfrequencies and radius

Laurent Piau, Remo Collet, Robert F. Stein +3

We study the effects of different descriptions of the solar surface convection on the eigenfrequencies of p-modes. 1-D evolution calculations of the whole Sun and 3-D hydrodynamic…
