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…
Cooling and Instabilities in Colliding Radiative Flows with Toroidal Magnetic Fields
R. N. Markwick, A. Frank, E. G. Blackman +6
We report on the results of a simulation based study of colliding magnetized plasma flows. Our set-up mimics pulsed power laboratory astrophysical experiments but, with an appropri…
How negative feedback and the ambient environment limit the influence of recombination in common envelope evolution
Luke Chamandy, Jonathan Carroll-Nellenback, Eric G. Blackman +5
We perform 3D hydrodynamical simulations to study recombination and ionization during the common envelope (CE) phase of binary evolution, and develop techniques to track the ionic…
Semantic Information in a model of Resource Gathering Agents
Damian R Sowinski, Jonathan Carroll-Nellenback, Robert N Markwick +5
We explore the application of a new theory of Semantic Information to the well-motivated problem of a resource foraging agent. Semantic information is defined as the subset of corr…
Morphology of Shocked Lateral Outflows in Colliding Hydrodynamic Flows
R. N. Markwick, A. Frank, J. Carroll-Nellenback +6
Supersonic interacting flows occurring in phenomena such as protostellar jets give rise to strong shocks, and have been demonstrated in several laboratory experiments. To study suc…
Opportunities for Technosignature Science in the Planetary Science and Astrobiology Decadal Survey
Jacob Haqq-Misra, Reza Ashtari, James Benford +13
Solar system exploration provides numerous possibilities for advancing technosignature science. The search for life in the solar system includes missions designed to search for evi…
Jets from main sequence and white dwarf companions during common envelope evolution
Yangyuxin Zou, Luke Chamandy, Jonathan Carroll-Nellenback +2
It has long been speculated that jet feedback from accretion onto the companion during a common envelope (CE) event could affect the orbital evolution and envelope unbinding proces…
Effects of Charge Exchange on the Evaporative Wind of HD 209458b
Alex Debrecht, Jonathan Carroll-Nellenback, Adam Frank +4
The role of charge exchange in shaping exoplanet photoevaporation remains a topic of contention. Exchange of electrons between stellar wind protons from the exoplanet's host star a…
Consensus between Epistemic Agents is Difficult
Damian R. Sowinski, Jonathan Carroll-Nellenback, Jeremy M. DeSilva +4
We introduce an epistemic information measure between two data streams, that we term . Closely related to transfer entropy, the measure must be estimated by epistemic ag…
Cooling and Instabilities in Colliding Flows
R. N. Markwick, A. Frank, J. Carroll-Nellenback +4
Collisional self-interactions occurring in protostellar jets give rise to strong shocks, the structure of which can be affected by radiative cooling within the flow. To study such…
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…
The Formation of Discs in the Interior of AGB Stars from the Tidal Disruption of Planets and Brown Dwarfs
Gabriel Guidarelli, Jason Nordhaus, Jonathan Carroll-Nellenback +3
A significant fraction of isolated white dwarfs host magnetic fields in excess of a MegaGauss. Observations suggest that these fields originate in interacting binary systems where…
Triggering A Climate Change Dominated "Anthropocene": Is It Common Among Exocivilizations?
Ethan Savitch, Adam Frank, Jonathan Carroll-Nellenback +3
We seek to model the coupled evolution of a planet and a civilization through the era when energy harvesting by the civilization drives the planet into new and adverse climate stat…

A microphysics model to describe the photoionization and impact ionization processes in dielectric ablator materials like plastic has been implemented into the one-dimensional hydr…
Common Envelope Evolution on the Asymptotic Giant Branch: Unbinding within a Decade?
Luke Chamandy, Eric G. Blackman, Adam Frank +2
Common envelope (CE) evolution is a critical but still poorly understood progenitor phase of many high-energy astrophysical phenomena. Although 3D global hydrodynamic CE simulation…
Bipolar Planetary Nebulae from Outflow Collimation by Common Envelope Evolution
