Hot Jupiter 🪐HD 143105 b has a mass of 1.2 Jupiters and an atmosphere dominated by water molecules. Its low atmospheric metallicity (0.1× solar) may explain the the observed lack of a thermal inversion

🪐AB Aurigae b's circumplanetary disk should emit thermal radiation from the dust, but none has been detected. Models however predict strong emission for protoplanet like this, hinting at limited dust supply near the planet

Three warm Jupiters and a Saturn-like planet discovered orbiting Sun-like stars ⭐️TOI-6628, ⭐️TOI-3837, ⭐️TOI-5027 and ⭐️TOI 2328. Their structures suggest rocky-icy cores with H/He atmospheres and formation via accretion
