Changes in granulation scales over the solar cycle seen with SDO/HMI and Hinode/SOT
J. Ballot, T. Roudier, J. M. Malherbe +1
The Sun is the only star where the superficial turbulent convection can be observed at very high spatial resolution. The Solar Dynamics Observatory (SDO) has continuously observed…
Photospheric downflows observed with SDO/HMI, HINODE, and an MHD simulation
T. Roudier, M. Švanda, J. M. Malherbe +3
Downflows on the solar surface are suspected to play a major role in the dynamics of the convection zone. We investigate the existence of the long-lasting downflows whose effects i…
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…
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…
Relation between trees of fragmenting granules and supergranulation evolution
Th. Roudier, J. M. Malherbe, M. Rieutord +1
Context: The determination of the underlying mechanisms of the magnetic elements diffusion over the solar surface is still a challenge. Understanding the formation and evolution of…
