XO-3 b exhibits a 30-70% deeper NUV transit depth of 0.1371 and a 22-minute late center relative to the optical ephemeris, with an extremely low estimated mass-loss rate and a bow-shock model that predicts the opposite timing direction.
TOI-159 b is confirmed as the hottest known eccentric hot Jupiter (e = 0.24) with a 13-sigma Keplerian detection around a young gamma Doradus star, including a preliminary low-resolution transmission spectrum.
Condensation temperature trends in JWST planet-host stars are independent of stellar and planetary properties after GCE correction, indicating mixed origins from galactic evolution and stellar processes.
New transit observations of WASP-43 b yield no evidence of orbital decay while revealing major challenges in combining multi-instrument data for atmospheric retrievals.
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.
