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.

Higher host-star C/O ratios correlate with longer orbital periods for giant planets, based on spectra from 598 stars and supported by pebble-formation models.
Selection effects in JWST transmission spectroscopy and HWO reflected-light imaging may cause the first biosignature detection to arise from an atypical planet rather than a representative Earth analog.
Sustained mass transfer from a circumbinary disc enables giant planet formation in gamma-Cephei-like binaries by prolonging the lifetime of the circumprimary disc against truncation and photoevaporation.
Simulations indicate that order-of-magnitude changes in TiO2 and SiO2 abundances in lava melts produce distinguishable TiO, SiO, and SiO2 features in dry lava planet emission spectra, potentially observable with 12 JWST eclipses for the brightest targets.
Tentative evidence for a super-Jupiter at 15-100 AU or brown dwarf at 20-170 AU in 51 Pegasi from RV curvature, but the signal is likely driven by Lick/Hamilton instrument drift.
NUV transit depth of XO-3b measured at 0.1371 with 22-minute late center; X-ray data yield mass-loss rate ~10^4 g/s; bow-shock model predicts early rather than late transit.
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.
