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…
Azimuthal brightness modulation reveals hidden rings in CI Tau
C. E. Scardoni, G. P. Rosotti, F. Zagaria +4
Protoplanetary disks often host substructures such as rings and gaps, which trace key processes in planet formation and dust evolution. However, narrow rings may remain unresolved…
Substructures in Planet-Forming Disks with the SKAO
Yinhao Wu, Jessica Speedie, Sebastián Pérez +33
Disks of gas and dust orbiting young stars are the arenas and material reservoirs for planet formation. Over the past decade, multiwavelength observations, from infrared to radio,…
Evidence for Systematically Larger Dust Grains in Upper Scorpius Relative to Taurus Disks
Yao Liu, Ilaria Pascucci, Fei Gao +10
Infrared spectroscopy provides a powerful diagnostic for probing the mineralogical properties of dust grains in the terrestrial planet-forming regions of protoplanetary disks. The…
Compact CO emission and no evidence of radial drift. ALMA observations of the faintest planet-forming disks in Lupus
Giulia Ricciardi, Francesco Zagaria, Anna Miotello +13
A large fraction of planet-forming disks observed with ALMA show faint CO emission, often interpreted as strong CO depletion. However, faint emission may also arise from spatially…
Astrometric view of companions in the inner dust cavities of protoplanetary disks
Miguel Vioque, Richard A. Booth, Enrico Ragusa +16
Protoplanetary disks with inner dust cavities (often referred to as "transition disks") are potential signposts of planet formation. We use Gaia astrometry to search for planetary…
