Earth Inner Core Anisotropy as Observed by PKiKP and PKIIKP Reflected Waves
… topic in understanding the planet’s core growth, magnetic dynamo, and evolution. Most data analysis techniques used to measure the anisotropy use the differential traveltimes between transmitted wave pairs, which mostly sample only shallow parts of the inner core or may be affected by mantle …

Plume formation in strongly temperature-dependent viscosity fluids: Application to early Mars
… the crust, which suggests that early Mars had a magnetic field. Investigation of the origin of these features provides insights into the early history of Mars as well as other terrestrial planets including Earth. We develop a hypothesis that the dichotomy is caused by an early transient …

Rotation and magnetism in massive stars
… to observed data. Models of rotationally-driven dynamos in stellar radiative zones have suggested that magnetohydrodynamic transport of angular momentum and chemical composition can dominate over the otherwise purely hydrodynamic processes. If this is the case then a proper consideration of the …

Magneto-thermal Instability in Dilute Magnetized Plasmas
… magnetised plasmas exchanges of heat across magnetic field lines are strongly suppressed, as charged particles rapidly gyrate around magnetic field lines but only infrequently scatter due to Coulomb collisions. The anisotropic heat conduction, in the presence of a large-scale temperature …
