TOI-4311 hosts a 0.99-day super-Earth (1.38 R_earth, 4.5 M_earth) and 15-day sub-Neptune (2.47 R_earth), plus a candidate 38-day planet, with the dense inner planet potentially challenging formation theories given the host's galactic population.

TOI-201 has three planets whose co-transiting configuration will end in 200 years due to Kozai-Lidov oscillations driven by mutual inclinations.
Archival RV and astrometric data plus three-body simulations constrain an unseen outer perturber in the GJ 436 system to sub-Jovian masses at a_c ≳ 6.8 AU, supporting Kozai-Lidov migration as the source of the hot Neptune's polar eccentric orbit.
WASP-96b shows super-solar metallicity of 2-6x stellar, roughly stellar C/O, tentative SO2 consistent with photochemistry, and an optical slope from scattering aerosols, supporting core-accretion formation beyond the water snowline.
Joint radial-velocity analysis revises GJ 3378b's period to 21.45 days and minimum mass to 2.3 Earth masses, placing the habitable-zone planet near the cosmic shoreline.
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.
New obliquity measurements for two Neptunes update the sample distribution to favor aligned systems plus a random component, resembling that of more massive planets and implying shared dynamical origins.
New transit data for WASP-11 b over 16 years shows no orbital decay or TTV signals from other planets, with a transmission spectrum exhibiting a strong Rayleigh scattering slope possibly from the atmosphere or contamination.
