The origin and dynamics of satellites

Conceptual illustration of material in an orbiting disk

01 / Giant-impact disks

Accretion in Giant-Impact Generated Disks

Investigation of accretion regimes (continuous, discrete, pyramidal).
Early dynamical evolution and migration of natural satellites.
Applications to the Earth–Moon system, Pluto–Charon, binary asteroids, and other terrestrial bodies.

02 / Ring–satellite interactions

Dynamical Interaction Between Rings and Satellites

Satellite migration driven by disk torques.
Gap opening and resonant interactions in particulate disks.
Applications to rings around planets and minor bodies.

03 / Exomoons

Formation and Detection of Exomoons

Investigation of post-impact disk conditions and subsequent disk evolution in exoplanetary systems.
Use of transit timing variations (TTV) and transit duration variations (TDV) for indirect detection.
Identification of exomoon signals in both synthetic and observational light curves.
