Effects of global core-mantle boundary topography on outer-core convection and topographic torques
Tobias G. Oliver, Eric G. Blackman, John A. Tarduno +1
Topography at the core-mantle boundary (CMB) couples the outer core to the mantle and likely generates observable variations in the length of day (LOD) and the geomagnetic field…
Early solar wind and dynamo magnetic field topology predictions for (16) Psyche and other asteroids
Atma Anand, Jonathan Carroll-Nellenback, Eric G. Blackman +1
Asteroid (16) Psyche is a metal-rich body that might record an ancient coherent magnetization if some relict crust or mantle is preserved. Herein, we use magnetohydrodynamic simula…
Thermal and magnetic evolution of an Earth-like planet with a basal magma ocean
Victor Lherm, Miki Nakajima, Eric G. Blackman
Earth's geodynamo has operated for over 3.5 billion years. The magnetic field is currently powered by thermocompositional convection in the outer core, which involves the release o…
Second-generation planet formation after tidal disruption from common envelope evolution
Luke Chamandy, Jason Nordhaus, Eric G. Blackman +1
We propose that certain white dwarf (WD) planets, such as WD 1856+534 b, may form out of material from a stellar companion that tidally disrupts from common envelope evolution with…
