kobra: a new Vlasov code intended for plasma-wall modeling
Sebastian Konewko, Nathan Maestracci, Sven Van Loo
In a fusion device plasma-wall interactions \edit{on the sheath scale} can be modeled as a collisionless problem. When modeling these regions particle-in-cell codes suffer from sta…
Modeling of plasma transport during edge-localized mode in tokamak using a kinetic Vlasov-Poisson code

Modelling grain-size distributions in C-type shocks using a discrete power-law model
Rosie Sumpter, Sven Van Loo
In this paper we discuss the implementation of a discrete, piecewise power-law grain-size distribution method into a numerical multifluid MHD code as described in Sumpter (2020). S…
Size-selective accretion of dust onto CPDs: Low CPD masses and filtration of larger grains
Samuel M. Karlin, Olja Panić, Sven van Loo
The major satellites of Jupiter and Saturn are believed to have formed in circumplanetary discs, which orbit forming giant protoplanets. Gas and dust in CPDs have different distrib…

Exploring dust growth in the episodic WCd system WR140
J. W. Eatson, J. M. Pittard, S. Van Loo
The wind collision region (WCR) in a colliding wind binary (CWB) is a particularly violent place, as such, it is surprising that it is also a region where significant quantities of…

J. W. Eatson, J. M. Pittard, S. Van Loo
Dust production is one of the more curious phenomena observed in massive binary systems with interacting winds. The high temperatures, UV photon flux and violent shocks should dest…
