Observability of planet-disc interactions in CO kinematics
(Oxford University Press, 2018)
Empirical evidence of planets in gas-rich circumstellar discs is required to constrain giant planet formation theories. Here we study the kinematic patterns which arise from planet- disc interactions and their observability ...
ALMA images of discs: are all gaps carved by planets?
(Oxford Univ Press, 2015)
Protoplanetary discs are now routinely observed and exoplanets, after the numerous indirect
discoveries, are starting to be directly imaged. To better understand the planet formation
process, the next step is the detection ...
Migration-driven diversity of super-Earth compositions
(2018-01-01)
A leading model for the origin of super-Earths proposes that planetary embryos migrate inward and pile up on close-in orbits. As large embryos are thought to preferentially form beyond the snowline, this naively predicts ...
Constraining the properties of transitional discs in Chamaeleon I with Herschel
(Oxford Univ Press, 2016)
Transitional discs are protoplanetary discs with opacity gaps/cavities in their dust distribution, a feature that may be linked to planet formation. We perform Bayesian modelling of the three transitional discs SZ Cha, CS ...
Formation of planetary systems by pebble accretion and migration: Growth of gas giants
(2019-03-01)
Giant planets migrate though the protoplanetary disc as they grow their solid core and attract their gaseous envelope. Previously, we have studied the growth and migration of an isolated planet in an evolving disc. Here, ...
The importance of thermal torques on the migration of planets growing by pebble accretion
(Wiley Blackwell Publishing, Inc, 2021-11)
A key process in planet formation is the exchange of angular momentum between a growing planet and the protoplanetary disc, which makes the planet migrate through the disc. Several works show that in general low-mass and ...
Building the Galilean moons system via pebble accretion and migration: A primordial resonant chain
(2021-06-01)
The origins of the Galilean satellites - namely Io, Europa, Ganymede, and Callisto - is not fully understood yet. Here we use N-body numerical simulations to study the formation of Galilean satellites in a gaseous ...
