Update on Early Asteroid Magnetization

Convergence Plot of Uniform Resistivity Simulation

Plotted the rate of change of Amplification as a function of Max field in each frame for all cases with uniform resisitivity structure and 2 winds (1000 #/cc and 300 #/cc).

We can see that those with high resisitivity start off with Amplification lower than the theoretical predicted max amplification limit and then increase towards their final steady state, while the ones with high conductivity start at high amplification and then decrease to steady state. (Kinks are due to restart with change in boundary conditions and buffer zones.)

New Lunar Proposal

We are trying to submit a proposal for study of lunar samples. Need to simulate the amplification for the present day moon, moon at 3.8 Ga and moon with thin atmosphere at 3.8 Ga.

Most recent experimental data of moon resistivity profile (from Apollo 12): https://www.dropbox.com/s/njoecnc9zvihuzh/dyal1976.png

Approximation of above data into models from recent data (Shimizu et al. 2013): https://www.dropbox.com/s/jzsk7tbtcglf9d6/shimizu2013.png

HEDSA Talk

HEDSA is organizing a series of talk about the future of Frontier Plasma Science. There will be a talk given by Carolyn Kuranz next week, Monday June 1 at 4pm EDT and I (Prof. Pierre Gourdain) was hoping that you could join the discussion. It is also very important to get students involved because we will be discussing something directly impact you. So, I would encourage you to reach out to all graduate students you know (get that Rolodex smoking), so they can ask questions using the Google form link ​https://forms.gle/4DupvDRRJKBn8p537

(Email me for link to the Zoom meeting.)
