Automated detection of exploding granules with SDO/HMI data
J. Ballot, T. Roudier
Exploding granules on the solar surface play a major role in the dynamics of the outer part of the convection zone, especially in the diffusion of the magnetic field. We aim to dev…
Texture of average solar photospheric flows and the donut-like pattern
T. Roudier, J. Ballot, J. M. Malherbe +1
Detailed knowledge of surface dynamics is one of the key points in understanding magnetic solar activity. The motions of the solar surface, to which we have direct access via the o…
Three-dimensional imaging of convective cells in the photosphere of Betelgeuse
A. López Ariste, S. Georgiev, Ph. Mathias +5
Understanding convection in red supergiants and the mechanisms that trigger the mass loss from these evolved stars are the general goals of most observations of Betelgeuse and its…
Evolution of exploding granules from coordinated observations by THEMIS, IRIS, SDO/HMI, and HINODE, and a simulation
T. Roudier, J. M. Malherbe, B. Gelly +3
Exploding granules constitute the strongest horizontal flows on the quiet Sun and contribute to the structure of the surface horizontal velocity fields which build the large-scale…
Link between trees of fragmenting granules and deep downflows in MHD simulation
T. Roudier, J. M. Malherbe, R. F. Stein +1
Trees of fragmenting granules (TFG) and associated flows are suspected to playa major role in the formation of the network in the quiet Sun. We investigate the counterparts, in ter…
Horizontal photospheric flows trigger a filament eruption
T. Roudier, B. Schmieder, B. Filippov +2
A large filament composed principally of two sections erupted sequentially in the southern hemisphere on January 26 2016. The central, thick part of the northern section was first…
