Flyby-induced high-eccentricity migration and the prevalence of hot Jupiters in M67

Mika V. Kontiainen, Cathie J. Clarke, Andrew J. Winter

Few planetary systems form in isolation. Rather, interactions in their birth environments may sculpt their architectures or drive them into unstable configurations. Here we study t…

Dust trapping, collisional velocity and velocity dispersion in gravito-turbulent discs

Cristiano Longarini, Cathie J. Clarke, Richard A. Booth +1

High-resolution ALMA observations indicate that planet formation is already well underway in the earliest stages of disc evolution, when discs are typically massive enough to be re…

Angular Momentum of Planet-Forming Disks: Implications for Infall Driven Misalignments

Aashish Gupta, Cristiano Longarini, L. Ilsedore Cleeves +5

Context. A significant fraction (>30%) of planet-forming disks and planetary are misaligned with respect to the rotational axis of their host stars, yet the dominant mechanism resp…

Can giant impacts be directly detected in other star systems?

Pavan Tanna, Simon Lock, Amy Bonsor +2

Giant impacts, collisions between planet-sized bodies, play an important role in planet and moon formation. As we enter a new era of large-scale surveys, such as \textit{Gaia} and…

Accretion bottleneck in protoplanetary discs: the role of the stellar spin

Cristiano Longarini, Cathie Clarke

We investigate angular momentum transport and accretion properties in a sample of protoplanetary discs with dynamical measurements of stellar masses, disc masses, and scale radii.…

Eccentric discs as a gateway to giant planets outward migration

Chiara E. Scardoni, Giovanni P. Rosotti, Cathie J. Clarke +2

Recent studies on planet-dominated Type II migration demonstrated the presence of a correlation between the direction of planet migration and the parameter K describing the depth o…
