1+ day, 7+ hour ago  (199+ words) Most modern atmospheric retrievals adopt the simplifying assumption that the planetary atmosphere endures no planetary rotation and stellar tidal effect. However, for tidally locked close-in exoplanets, the gravitational influence of the host star and the rapid rotation of the planet…...

1+ day, 7+ hour ago  (129+ words) Uranus and Neptune are commonly interpreted as volatile-rich "ice giants, an assumption that underpins most interior models. Our results, based on three fit parameters for each planet, provide a parsimonious explanation for the structures, thermal states, and atmospheric chemistries of…...
