Overview
- Researchers imaged faint debris belts around young stars with ALMA at unprecedented detail, overcoming the extreme faintness of these systems.
- The dataset reveals diverse architectures, including multi-ring belts, smooth extended halos, sharp edges, arcs and clumps that the team interprets as planetary perturbations.
- ARKS mapped dust emission in all 24 disks and charted carbon monoxide gas in six gas-rich systems, enabling combined structural and chemical analyses.
- The results appear in a series of peer-reviewed papers in Astronomy & Astrophysics, providing a public resource for further study.
- The collaboration has begun complementary direct-imaging and radial-velocity campaigns to test the planetary origin of the observed features and to find the suspected young planets.
