- Magnus Haw received his PhD degree in June 2018 and has become a Research Associate at the NASA Ames Research Center where he will be working on plasma issues associated with spacecraft re-entry.
- The paper by Magnus Haw et al. titled Reverse Current Model for Coronal Mass Ejection Cavity Formation. in Astrophysical Journal Letters shows that the cavities in solar coronal mass ejections result from a void formed when an external image reverse electric current induced by a rising core electric current is repelled by the core current.
- The paper by Paul Bellan titled Model for how an accretion disk drives astrophysical jets and sheds angular momentum. in Plasma Physics and Controlled Fusion shows how gravitational energy released by accreting matter acts as a power supply that drives astrophysical jets while at the same time shedding angular momentum.
- The paper by Magnus Haw and Paul Bellan MHD collimation mechanism in arched flux ropes characterized using volumetric, time‐dependent B‐vector measurements is an “Editor’s Highlight” in Geophysical Research Letters.
- Young Dae Yoon gave an invited talk at the 2017 American Physical Society Division of Plasma Physics annual meeting on a new way of explaining fast magnetic reconnection. The talk is A generalized two-fluid picture of non-driven collisionless reconnection and its relation to whistler waves
- Paul Bellan gave a tutorial talk at the 2017 American Physical Society Division of Plasma Physics annual meeting on Experiments and models of MHD jets and their relevance to astrophysics and solar physics.
- Measurements made by the MMS spacecraft reported by Gershman et al. in the paper Wave-particle energy exchange directly observed in a kinetic Alfvén-branch wave in Nature Communications validate the method proposed by Paul Bellan in the paper Revised Single-Spacecraft Method for Determining Wavevector k and Resolving Space-time Ambiguity. This method shows how a single spacecraft can measure the wavelength and direction of a low-frequency plasma wave so four spacecraft are not needed as was previously presumed.
