Probing the final stages of protoplanetary disk evolution with ALMA
(EDP Sciences, 2015)
Context. The evolution of a circumstellar disk from its gas-rich protoplanetary stage to its gas-poor debris stage is not understood well. It is apparent that disk clearing progresses from the inside-out on a short time ...
Searching for faint comoving companions to the alpha Centauri system in the VVV survey infrared images
(Oxford university press, 2017)
The VVV survey has observed the southern disc of the Milky Way in the near-infrared, covering 240 deg(2) in the ZYJHKs filters. We search the VVV survey images in a similar to 19 deg(2) field around alpha Centauri, the ...
Stellar multiplicity and debris discs: an unbiased sample
(Oxford University Press, 2015)
Circumstellar dust discs have been observed around many nearby stars. However, many
stars are part of binary or multiple stellar systems. A natural question arises regarding the
presence and properties of such discs in ...
94 Ceti: a triple star with a planet and dust disc
(OXFORD UNIV PRESS, 2016)
94 Ceti is a triple star system with a circumprimary gas giant planet and far-infrared excess. Such excesses around main sequence stars are likely due to debris discs, and are considered as signposts of planetary systems ...
Very Large Telescope observations of Gomez's Hamburger: Insights into a young protoplanet candidate
(ESO, 2015)
Planets are thought to form in the gas and dust disks around young stars. In particular, it has been proposed that giant planets can form through the gravitational instability of massive extended disks around intermediate-mass ...
The complex morphology of the young disk MWC 758: spirals and dust clumps around a large cavity
(IOP Publishing Ltd, 2018)
We present Atacama Large Millimeter Array observations at an angular resolution of 0 ''.1-0 ''.2 of the disk surrounding the young Herbig Ae star MWC. 758. The data consist of images of the dust continuum emission recorded ...
Multiple planetary systems: Properties of the current sample
(Elsevier Science, 2017-08)
We carry out analyses on stellar and planetary properties of multiple exoplanetary systems in the currently available sample. With regards to the stars, we study their temperature, distance from the Sun, and metallicity ...
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 ...
