The critical obstacle size to generate a compressed plasma region ahead of these objects is determined by independently varying the magnitude of the dipolar magnetic moment and the plasma magnetization. We find that the effective size of the obstacle depends on the relative orientation between the dipolar and plasma internal magnetic fields, and we show that this may be critical to form a shock in small-scale structures. We study the microphysics of the magnetopause in different magnetic field configurations in 2D and compare the results with full 3D simulations. Finally, we evaluate the parameter range where such miniature magnetized shocks can be explored in laboratory experiments. Published by AIP Publishing.[http://dx

Electron acceleration by wave turbulence in a magnetized plasma

“…OSIRIS simulation results indicate, in agreement with our previous FLASH simulations, that as the plasma impacts the sphere (of typical size larger than the ion Larmor radius), a bow shock develops [23]. The counterpropagating ion flow is unstable and excites plasma waves in the lower-hybrid range ahead of the shock front (see Figure 4).…”

A platform for high-repetition-rate laser experiments on the Large Plasma Device

“…Future work will utilize thousands of shots to correlate fluctuations in the magnetic and electric fields and determine the instability growth rate [28] . Kinetic-scale magnetospheres are also possible to explore by coupling the laser plasma with an ion-scale ( ) magnetic dipole field [29] . Of particular interest is the dynamics and 3D structure of the interaction between a super-Alfvénic flow and the dipole field, which can be mapped out at high resolution over thousands of shots.…”

3d Pic Simulations of Collisionless Shocks at Lunar Magnetic Anomalies and Their Role in Forming Lunar Swirls

“…The computational investigation into mini-magnetospheres has become an area of considerable interest. A number of papers on hybrid (Bamford et al 2008;Gargaté et al 2008;Kallio et al 2012;Poppe et al 2012) and particle-in-cell (PIC) (Kallio et al 2012;Bamford et al 2013aBamford et al , 2013bBamford et al , 2015Deca et al 2014Deca et al , 2015Jarvinen et al 2014;Cruz et al 2015Cruz et al , 2016Dyadechkin et al 2015;Fatemi et al 2015) simulations have been authored, following from previous magnetohydrodynamic (MHD) simulations (Harnett & Winglee 2002Kurata et al 2005). Here we perform fully self-consistent PIC simulations in 2D and 3D, with a realistic proton-to-electron mass ratio.…”
