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…
The formation and structure of iron-dominated planetesimals
Terry-Ann Suer, Edgar S. Steenstra, Simone Marchi +2
Metal-rich asteroids and iron meteorites are considered core remnants of differentiated planetesimals and or products of oxygen-depleted accretion. Investigating the origins of iro…
Turbulence in Earth's core generates large topographic torques on the mantle
Tobias G. Oliver, Eric G. Blackman, John A. Tarduno +1
Seismic and geodynamic studies indicate that the boundary between the Earth's liquid outer core and solid mantle is not spherical, but is likely characterized by topography in the…
Terrestrial atmospheric ion implantation occurred in the nearside lunar regolith during the history of Earth's dynamo
Shubhonkar Paramanick, Eric G. Blackman, John A. Tarduno +1
Light volatile elements in lunar regolith are thought to be a mixture of the solar wind and Earth's atmosphere, the latter sourced in the absence of geomagnetic field. However, the…
