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…

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…

Seeing the unseen: a method to detect unresolved rings in protoplanetary disks
Chiara E. Scardoni, Richard A. Booth, Cathie J. Clarke +2
While high resolution ALMA observations reveal a wealth of substructure in protoplanetary discs, they remain incapable of resolving the types of small scale dust structures predict…
