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 ...
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 ...
A ring-like concentration of mm-sized particles in Sz 91
(Oxford Univ Press, 2016)
Models of planet formation and disc evolution predict a variety of observables in the dust structure of protoplanetary discs. Here, we present Atacama Large Millimeter/submillimeter Array (ALMA) Band-6 and Band-7 observations ...
Magnetic fields in protoplanetary discs: from MHD simulations to ALMA observations
(Oxford University Press, 2017-01)
Magnetic fields significantly influence the evolution of protoplanetary discs and the formation of planets, following the predictions of numerous magnetohydrodynamic (MHD) simulations. However, these predictions are yet ...
Circumbinary, not transitional: On the spiral arms, cavity, shadows, fast radial flows, streamers, and horseshoe in the HD142527 disc
(Oxford University Press, 2018)
We present 3D hydrodynamical models of the HD142527 protoplanetary disc, a bright and
well studied disc that shows spirals and shadows in scattered light around a 100 au gas cavity, a
large horseshoe dust structure in ...
Circumbinary, not transitional: on the spiral arms, cavity, shadows, fast radial flows, streamers, and horseshoe in the HD 142527 disc
(Oxford University Press, 2018)
We present 3D hydrodynamical models of the HD 142527 protoplanetary disc, a bright and well-studied disc that shows spirals and shadows in scattered light around a 100 au gas cavity, a large horseshoe dust structure in mm ...
Rings and gaps in the disc around Elias 24 revealed by ALMA
(Oxford University Press, 2018)
We present Atacama Large Millimeter/sub-millimeter Array (ALMA) Cycle 2 observations of the 1.3-mm dust continuum emission of the protoplanetary disc surrounding the T Tauri star Elias 24 with an angular resolution of ...
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, ...
HD 169142 in the eyes of ZIMPOL/SPHERE
(Oxford University Press, 2018)
We present new data of the protoplanetary disc surrounding the Herbig Ae/Be star HD 169142 obtained in the very broad-band (VBB) with the Zurich imaging polarimeter (ZIMPOL), a sub-system of the Spectro-Polarimetric ...
