Planetesimal disks with 1-4% of the planetary mass disrupt resonant Neptune chains, triggering instabilities that scatter planets to ~0.1 au orbits and enable hot Neptune formation on 10-100 Myr timescales.
Three accelerating stars yield one stellar companion at 166 AU, one 45 Jupiter-mass object at ~18 AU, and one 9.5 Jupiter-mass object at 6.4 AU that is 65% likely to be a planet.
An optimal Stokes number window of 0.01-0.03 allows streaming instability to form planetesimals and pebble accretion to build all three main planet classes, with cold gas giants needing the lowest turbulence and largest discs.
Giant planet formation traps dust in pressure bumps and planetesimal formation converts dust to larger bodies, making evolved disk masses appear low as a natural outcome of these processes, with models matching observations best for initial disk masses of 4-7% solar mass.
A single critical RV observation enhances recovery of long-period super-Jupiters by 3.5 times for Saturn-like periods in injection-recovery tests bridging HIRES and KPF baselines.
Gaia astrometric quality metrics and a machine-learning classifier trained on known exoplanet hosts identify candidate stars with debris disks likely to host undetected planets.
Giant planet multiplicity is low, with 10.6% and 15.8% of Sun-like stars hosting at least one giant planet within 10 au across the two surveys, mostly as singles, inconsistent with scattering models.
Reviews direct imaging of protoplanets and proposes deriving observational estimates of planet mass-to-radius ratio to test formation models, highlighting ELT capabilities.

Exploring the conditions for forming planetesimals by the streaming instability and planetary systems by pebble accretion
An optimal Stokes number window of 0.01-0.03 allows streaming instability to form planetesimals and pebble accretion to build all three main planet classes, with cold gas giants needing the lowest turbulence and largest discs.
