Bridging magnetothermal winds and photoevaporation to model discs dispersal
Giovanni Picogna, Barbara Ercolano
Protoplanetary disc dispersal is driven by two processes usually modelled separately: photoevaporative and magnetohydrodynamic (MHD) disc winds. Global simulations indicate that in…
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…
The dispersal of compact protoplanetary discs
Giovanni Picogna, Barbara Ercolano
Compact protoplanetary discs are becoming increasingly prominent in observations. Their dispersal pathways may differ substantially from those of extended discs. We aim to quantify…
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…
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…
Photoevaporation of protoplanetary discs with PLUTO+PRIZMO I. Lower X-ray-driven mass-loss rates due to enhanced cooling
Andrew D. Sellek, Tommaso Grassi, Giovanni Picogna +3
Context: Photoevaporation is an important process for protoplanetary disc dispersal but there has so far been a lack of consensus from simulations over the mass-loss rates and the…
