Planet formation in a triple stellar system: implications of the third star's orbital inclination
(Cambridge Univ Press, 2015)
Core instability models of giant planet accretion and the planetary desert
(Wiley Blackwell Publishing, Inc, 2008-12)
With the aim of studying the final mass distribution of extrasolar planets, we have developed a simple model based on the core instability model, which allows us to form a large population of planets and make them evolve ...
Sublimation of icy planetesimals and the delivery of water to the habitable zone around solar type stars
(Wiley Blackwell Publishing, Inc, 2018-09)
We present a semi-analytic model to evaluate the delivery of water to the habitable zone (HZ) around a solar type star carried by icy planetesimals born beyond the snow line. The model includes sublimation of ice, gas drag, ...
Resolving the planetesimal belt of HR 8799 with ALMA
(Oxford University Press, 2016)
The star HR 8799 hosts one of the largest known debris discs and at least four giant planets. Previous observations have found evidence for a warm belt within the orbits of the planets, a cold planetesimal belt beyond their ...
The role of the initial surface density profiles of the disc on giant planet formation: comparing with observations
(Royal Astronomical Society, 2011-04)
In order to explain the main characteristics of the observed population of extrasolar planets and the giant planets in the Solar system, we need to get a clear understanding of which are the initial conditions that ...
Forming Jupiter, Saturn, Uranus and Neptune in few million years by core accretion
(Academic Press Inc Elsevier Science, 2009-12)
Giant planet formation process is still not completely understood. The current most accepted paradigm, the core instability model, explains several observed properties of the Solar System’s giant planets but, to date, has ...
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 ...
