The Astrophysical Journal LettersIn the standard formation models of terrestrial planets in the solar system and close-in super-Earths in nonresonant orbits recently discovered by exoplanet observations, planets are formed by giant impacts of protoplanets or planetary embryos after the ...

Magnetic fields in gaps surrounding giant protoplanets
, 2015 Giant protoplanets evacuate a gap in their host protoplanetary disc, which gas must cross before it can be accreted. A magnetic field is likely carried into the gap, potentially influencing the flow.

Dynamics of Small, Constant-size Particles in a Protoplanetary Disk with an Embedded Protoplanet
The Astrophysical JournalHydrodynamical simulations of protoplanetary disk dynamics are useful tools for understanding the formation of planetary systems, including our own. Approximations are necessary to make these simulations computationally tractable.

A Resonant Beginning for the Solar System’s Terrestrial Planets
The Astrophysical JournalIn the past two decades, transit surveys have revealed a class of planets with thick atmospheres—sub-Neptunes—that must have completed their accretion in protoplanet disks.
