Planet formation with envelope enrichment: new insights on planetary diversity [PDF]
, 2016 We compute, for the first time, self-consistent models of planet growth including the effect of envelope enrichment. The change of envelope metallicity is assumed to be the result of planetesimal disruption or icy pebble sublimation.

Can planetary instability explain the Kepler dichotomy?
, 2012 The planet candidates discovered by the Kepler mission provide a rich sample to constrain the architectures and relative inclinations of planetary systems within approximately 0.5 AU of their host stars.

On the Likelihood of Planet Formation in Close Binaries [PDF]
, 2015 To date, several exoplanets have been discovered orbiting stars with close binary companions (a~<30 AU). The fact that planets can form in these dynamically challenging environments implies that planet formation must be a robust process. The initial protoplanetary disks in these systems from which planets must form should be tidally truncated to radii ...

The Astrophysical Journal LettersGas surface density is one of the most relevant physical quantities in protoplanetary disks. However, its precise measurement remains highly challenging due to the lack of a direct tracer.

Low-mass Stars: Their Protoplanetary Disk Lifetime Distribution
The Astrophysical JournalWhile most protoplanetary disks lose their gas within less than 10 Myr, individual disk lifetimes vary from 5 Myr. The next challenge is to quantitatively link the diversity of disk lifetimes to the diversity in planets.

Giant Planet Formation and Migration
, 2018 Planets form in circumstellar discs around young stars. Starting with sub-micron sized dust particles, giant planet formation is all about growing 14 orders of magnitude in size.

Impact of planet--planet scattering on the formation and survival of debris disks
, 2014 Planet--planet scattering is a major dynamical mechanism able to significantly alter the architecture of a planetary system. In addition to that, it may also affect the formation and retention of a debris disk by the system.
