Dust torques for realistic dust size distributions
V. Roatti, G. Picogna, F. Marzari
Previous studies have shown that a population of dust particles with a fixed Stokes number can exert a substantial torque on a low-mass planet embedded in a protoplanetary disk, mo…
Dust distribution in circumstellar disks harboring multi-planet systems. II. Super-thermal mass planets
V. Roatti, G. Picogna, F. Marzari
Theoretical formation models and exoplanet detection surveys indicate that systems with multiple giant planets are common. We investigate how multiple super-thermal mass planets em…
From the Solar System to cosmological distances: a complete formalism for gravitational wave astrometry
Gabriele Perna, Nicola Bellomo, Vincenzo Roatti +1
The presence of a gravitational wave background (GWB) can be established not only via exquisitely precise pulsar timing array (PTA) measurements, but also via astrometric observati…
Dust distribution in circumstellar disks harboring multi-planet systems. I. Sub-thermal mass planets
V. Roatti, G. Picogna, F. Marzari
We investigate the formation of dust gaps in circumstellar disks driven by the presence of multiple low-mass planets, focusing on the distinct physical mechanisms that operate acro…
