Elongation and stability of a linear dune
O. Rozier, C. Narteau, C. Gadal +2
Compared to barchan dunes, the morphodynamics of linear dunes that elongate on a non-erodible bed is barely investigated by means of laboratory experiments or numerical simulations…
Blocked radiative heat transport in the hot pyrolitic lower mantle
Sergey S. Lobanov, Nicholas Holtgrewe, Gen Ito +8
The heat flux across the core-mantle boundary (QCMB) is the key parameter to understand the Earth/s thermal history and evolution. Mineralogical constraints of the QCMB require dec…
Periodicity in fields of elongating dunes
Cyril Gadal, Clément Narteau, Sylvain Courrech du Pont +2
Dune fields are commonly associated with periodic patterns that are among the most recognizable landscapes on Earth and other planetary bodies. However, in zones of limited sedimen…
Dynamo-based limit to the extent of a stable layer atop Earth's core
Thomas Gastine, Julien Aubert, Alexandre Fournier
The existence of a stably stratified layer underneath the core-mantle boundary (CMB) has been recently revived by corroborating evidences coming from seismic studies, mineral physi…
Machine Learning Reveals the Seismic Signature of Eruptive Behavior at Piton de la Fournaise Volcano
C. X. Ren, A. Peltier, V. Ferrazzini +3
Volcanic tremor is key to our understanding of active magmatic systems but, due to its complexity, there is still a debate concerning its origins and how it can be used to characte…
Middle-atmosphere dynamics observed with a portable muon detector
Matias Tramontini, Marina Rosas-Carbajal, Christophe Nussbaum +2
In the past years, large particle-physics experiments have shown that muon rate variations detected in underground laboratories are sensitive to regional, middle-atmosphere tempera…
