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 ...
Resolved carbon monoxide observations of protoplanetary discs in ophiuchus
(Universidad de Chile, 2022)
The $^{12}$CO rotational lines in protoplanetary discs are good tracers of the total spatial extension of the gas component and potentially planet-disc interactions. This work analyses ALMA long-baseline observations of ...
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 ...
Spiral arms in the protoplanetary disc HD100453 detected with ALMA: evidence for binary-disc interaction and a vertical temperature gradient
(Oxford Univ Press, 2020)
Scattered light high-resolution imaging of the protoplanetary disc orbiting HD100453 shows two symmetric spiral arms, possibly launched by an external stellar companion. In this paper, we present new, sensitive high-resolution ...
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 ...
Size and density sorting of dust grains in SPH simulations of protoplanetary discs
(OXFORD UNIV PRESS, 2017)
The size and density of dust grains determine their response to gas drag in protoplanetary discs. Aerodynamical (size x density) sorting is one of the proposed mechanisms to explain the grain properties and chemical ...
