Splinters
Splinter A (Hans Nilsson), Electric potential differences at space boundaries
In a recent paper we determined the electric potential of the observation point relative to the upstream solar wind at comet 67P. Similar estimates have been obtained near the bow shock at Mars using electrons and the cross shock potential at Earth based on electric field observations. In this splinter we will discuss observations of such electric potentials and see if we can learn something by comparing observations at different objects.
Splinter B (Savvas Raptis), Distribution functions & particle moments of high speed magnetosheath jets
In this splinter session, we will be discussing the properties of high speed magnetosheath jets based on how they appear on velocity distribution functions (VDFs), primarily using Magnetosphere Multiscale (MMS) mission. Some topics of discussion could include identification of jets, background estimation, partial moment derivation, discrepancies of their bulk properties, jet characterization, instabilities, excitation of waves, etc.
Splinter C (Martin Lindberg), Electron acceleration at quasi-perpendicular shocks
Quasi-perpendicular shocks are important sources for electron acceleration in our universe. Understanding the acceleration mechanisms at these shocks will help solving the long standing electron injection problem. One of the most promising theories are the Stochastic Shock Drift Acceleration theory. However, few experimental evidence for this theory is present today and in order to validate this theory, more is needed.
Splinter D (Nickolay Ivchenko), Sounding rockets
If there is sufficient interest (i.e. if the people involved intend to attend) we could discuss ongoing and future sounding rocket projects.
Splinter E (Herbert Gunell), Diamagnetic cavities & min-magnetospheres in laser-plasma experiments
In recent years, laboratory experiments with laser-produced plasmas have been able to create phenomena that we know from space, such as shocks and diamagnetic cavities. One example of this are two paper published in this year:
doi:10.1063/5.0084353 which present an experiment
doi:10.1063/5.0084354 describing simulations of it. In this splinter we shall discuss whether experiments such as these can help us understand comets and mini-magnetospheres, such as those created by the crustal fields on the moon.
