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…
A Quadruple Excess in Wide Binary Systems: Evidence for Correlated Binary Formation
Dolev Bashi, Cathie J. Clarke, Vasily Belokurov
Understanding the multiplicity of stellar systems and the correlations between their hierarchical components provides crucial insights into star formation processes. If binary comp…
A Quality Framework for Testing Gravity with Wide Binaries: No Evidence for MOND
Stephen A. Cookson, Indranil Banik, Kareem El-Badry +4
Wide binaries (WBs) offer a unique opportunity to test gravity in the low-acceleration regime, where modifications such as Milgromian dynamics (MOND) predict measurable deviations…
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…
