Tracing Methamphetamine abuse in under-treatment drivers: How biomechanical and oculomotor features help detect at-risk drivers?

Hamed Salmanzadeh, Alireza Mortezapour, Iman Tahbazzadeh Moghaddam +3

While the detrimental impacts of driving under the influence of stimulants such as methamphetamine are well-documented, the driving performance of individuals currently under-treat…

Reading between the rings: observed dust ring properties as probes of planet masses

Amena Faruqi, Jessica Speedie, Ralph E. Pudritz +1

We hypothesise that dust rings in protoplanetary discs formed by an embedded planet should have properties that reflect the planet's mass. We use 2D hydrodynamical simulations of p…

Disc fragmentation. II. Ejection of low mass Free Floating Planets from growing binary systems

Sergei Nayakshin, Luyao Zhang, Aleksandra Ćalović +4

Observations indicate that disc fragmentation due to Gravitational Instability (GI) is the likely origin of massive companions to stars, such as giant planets orbiting M-dwarf star…

Leading & Trailing Spiral Arms in a Nearly Broken Protoplanetary Disc

Sahl Rowther, Rebecca Nealon, Richard Alexander +1

We perform three-dimensional smoothed particle hydrodynamics simulations to investigate the formation of spiral arms in misaligned circumbinary discs. In a nearly broken disc the m…

Dust density enhancements and the direct formation of planetary cores in gravitationally unstable discs

Ken Rice, Hans Baehr, Alison K Young +5

Planet formation via core accretion involves the growth of solids that can accumulate to form planetary cores. There are a number of barriers to the collisional growth of solids in…

Short-Lived Gravitational Instability in Isolated Irradiated Discs

Sahl Rowther, Daniel J. Price, Christophe Pinte +3

Irradiation from the central star controls the temperature structure in protoplanetary discs. Yet simulations of gravitational instability typically use models of stellar irradiati…
