Tracking granules at the Sun's surface and reconstructing velocity fields. II. Error analysis
R. Tkaczuk, M. Rieutord, N. Meunier +1
The determination of horizontal velocity fields at the solar surface is crucial to understanding the dynamics and magnetism of the convection zone of the sun. These measurements ca…
Tracking granules on the Sun's surface and reconstructing horizontal velocity fields: I. the CST algorithm
M. Rieutord, T. Roudier, S. Roques +1
Determination of horizontal velocity fields on the solar surface is crucial for understanding the dynamics of structures like mesogranulation or supergranulation or simply the dist…
On the dynamics of radiative zones in rotating stars
M. Rieutord
In this lecture I try to explain the basic dynamical processes at work in a radiative zone of a rotating star. In particular, the notion of baroclinicity is thoroughly discussed. A…
A simulation of solar convection at supergranulation scale
M. Rieutord, H. -G. Ludwig, T. Roudier +2
We present here numerical simulations of surface solar convection which cover a box of 303.2 Mm with a resolution of 31582, which is used to in…
Are granules good tracers of solar surface velocity fields?
M. Rieutord, T. Roudier, H. -G. Ludwig +2
Using a numerical simulation of compressible convection with radiative transfer mimicking the solar photosphere, we compare the velocity field derived from granule motions to the a…
