Formation of stars, substellar objects and exoplanets : Observations of multiplicity [PDF]
, 2011 Many nearby stars are part of a binary or multiple system. Details about their history are preserved in their multiplicity characteristics, and observations of binary/multiple star systems provide a way to measure fundamental physical properties of the stars as well as clues to their formation and evolution.

The Astrophysical JournalAtmospheric compositions of sub-Neptunes and super-Earths are often interpreted as tracers of formation location relative to volatile ice lines. However, prolonged magma oceans can chemically equilibrate with primordial atmospheres and modify accreted ...

Are WASP-107-like Systems Consistent with High-eccentricity Migration?
The Astrophysical JournalWASP-107 b seems to be a poster child of the long-suspected high-eccentricity migration scenario. It is on a 5.7 day, polar orbit. The planet is Jupiter-like in radius but Neptune-like in mass with exceptionally low density.

TOI-880 is an Aligned, Coplanar, Multiplanet System
The Astronomical JournalAlthough many cases of stellar spin–orbit misalignment are known, it is usually unclear whether a single planet’s orbit was tilted or if the entire protoplanetary disk was misaligned.

Mapping out the time-evolution of exoplanet processes [PDF]
, 2019 There are many competing theories and models describing the formation, migration and evolution of exoplanet systems. As both the precision with which we can characterize exoplanets and their host stars, and the number of systems for which we can make ...

Planet Mass Function around M Stars at 1–10 au: A Plethora of Sub-Earth Mass Objects
The Astrophysical JournalSmall planets (≲1 M _⊕ ) at intermediate orbital distances (∼1 au) represent an uncharted territory in exoplanetary science. The upcoming microlensing survey by the Nancy Grace Roman Space Telescope will be sensitive to objects as light as Ganymede and ...
