Astronomers Discover Inflated Hot Neptune Exoplanet

A new preprint details the discovery and characterization of TOI-2195 A b, an inflated hot Neptune exoplanet. This planet orbits an early K-type star and has a wide binary companion, completing an orbit every 4.16 days. Its unique characteristics, including a near-polar orbit, challenge existing models of planetary formation and evolution, offering new data for astrophysical theories.
