Like the other hot Neptune, this one's atmosphere appears negligible. Nevertheless, it might not have a rocky surface — it might be a "water world." "The core of the planet is rocky, but there could be a huge layer of water on top of the core, partially in supercritical form," Naponiello says.We investigate the formation of multiple-planet systems in the presence of a hot Jupiter (HJ) using extended N-body simulations that are performed simultaneously with semianalytic calculations.Our primary aims are to describe the planet formation process starting from planetesimals using high-resolution simulations, and to examine the dependences of the architecture of planetary systems on ...The relative "hot spot" is due to Neptune's axial tilt, which has exposed the south pole to the Sun for the last quarter of Neptune's year, or roughly 40 Earth years. As Neptune slowly moves towards the opposite side of the Sun, the south pole will be darkened and the north pole illuminated, causing the methane release to shift to the north pole.Mysteriously, scientists haven't found many ultra-short-period planets of intermediate size, a phenomenon dubbed the "hot Neptune desert" because Neptune lies between Earth and Jupiter in size. Now, scientists have discovered an exoplanet that sits right in the hot Neptune desert. But this planet is much hotter than any hot Neptune discovered ...
