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.
A forward-modeling framework called TAED combines multi-technique exoplanet samples over Galactic scales and recovers demographic parameters accurately from simulated Kepler transit data using differential evolution optimization.
ALMA observations of 100 Ophiuchus discs show substructures linked to giant planet formation are common in discs above 10 Earth masses of dust and increase from Class I to Class II stages.
Self-lensing signals occur with probabilities of roughly 10^{-3} in WD+NS systems and 10^{-2} in WD+BH systems; TESS could detect at least one if 8% of white dwarfs have NS companions and 3% have BH companions, while Roman cannot.
Three anomalous microlensing events are re-modeled as binary-lens binary-source (2L2S) systems that resolve prior residuals, with source stars identified as G8V/M3V, G8V/K2V, and G6V/G8V pairs and lenses inferred as low-mass binaries via Bayesian methods.
Three new planets detected via 2023 KMTNet microlensing with mass ratios log q ~ -1.9, -2.0, -2.6; overall 2023 sample of 25 planets matches prior mass-ratio distribution.
A new HST wide-field survey of the Galactic Bulge supplies high-angular-resolution data to enhance Roman exoplanet detections and serve as a community legacy dataset for stellar populations and dynamics.
A hyperbolic secant profile with standard deviation 0.328 pixels best fits charge diffusion in the Roman detector across 850-2000 nm with no detectable wavelength dependence.
Archival MIRI imaging reaches contrasts of 10^-3 to 10^-4 at 1-3 arcseconds, enabling detection of ~170 K Jupiter-sized planets at separations >35 AU around M-dwarfs at 12.5 pc, with no new planets found but useful sensitivity maps produced.
An updated SynthPop model matches most bulge stellar and kinematic data but overpredicts optical microlensing event rates by about 20 percent near the galactic plane.

Self-Lensing Signals in Binary Systems Containing White Dwarfs with Neutron star or Stellar-mass Black hole Companions
Self-lensing signals occur with probabilities of roughly 10^{-3} in WD+NS systems and 10^{-2} in WD+BH systems; TESS could detect at least one if 8% of white dwarfs have NS companions and 3% have BH companions, while Roman cannot.
