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…

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…

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…

Asteroid Magnetization from the Early Solar Wind

Atma Anand, Jonathan Carroll-Nellenback, Eric G. Blackman +1

Magnetic fields provide an important probe of the thermal, material, and structural history of planetary and sub-planetary bodies. Core dynamos are a potential source of magnetic f…

Mass, energy, and momentum capture from stellar winds by magnetized and unmagnetized planets: implications for atmospheric erosion and habitability

Eric G. Blackman, John A. Tarduno

The extent to which a magnetosphere protects its planetary atmosphere from stellar wind ablation depends upon how well it prevents energy and momentum exchange with the atmosphere…

Detecting the oldest geodynamo and attendant shielding from the solar wind: Implications for habitability

John A. Tarduno, Eric G. Blackman, Eric E. Mamajek

The onset and nature of the earliest geomagnetic field is important for understanding the evolution of the core, atmosphere and life on Earth. A record of the early geodynamo is pr…
