Seismic Oscillations Excited by Giant Impacts in Directly Imaged Giant Planets

The Astrophysical Journal
The radii and masses of many giant exoplanets imply their interiors each contain more than ∼100 M _⊕ of solids. A large metal content may arise when a giant planet grows by colliding and merging with multiple ∼10 M _⊕ solid cores.

Tests of In-Situ Formation Scenarios for Compact Multiplanet Systems

, 2014
Kepler has identified over 600 multiplanet systems, many of which have several planets with orbital distances smaller than that of Mercury -- quite different from the Solar System. Because these systems may be difficult to explain in the paradigm of core

On the Exoplanet Yield of Gaia Astrometry

The Astronomical Journal
We reexamine the expected yield of Gaia astrometric planet detections using updated models for giant-planet occurrence, the local stellar population, and Gaia’s demonstrated astrometric precision. Our analysis combines a semianalytic model that clarifies

Formation of terrestrial planet cores inside giant planet embryos

, 2010
Giant planet embryos are believed to be spawned by gravitational instability in massive extended (R ~ 100 AU) protostellar discs. In a recent paper we have shown that dust can sediment inside the embryos, as argued earlier by Boss (1998) in a slightly ...

The Gemini Planet Imager Exoplanet Survey: Giant Planet and Brown Dwarf Demographics From 10-100 AU

, 2019
We present a statistical analysis of the first 300 stars observed by the Gemini Planet Imager Exoplanet Survey (GPIES). This subsample includes six detected planets and three brown dwarfs; from these detections and our contrast curves we infer the ...
