We have discovered over 5,000 planets around other star systems. Amongst the veritable cosmic menagerie of exoplanets, it seems there is a real shortage of Neptune-sized planets close to their star. A new paper just published discusses a Saturn-sized planet close to its host star which should be experiencing mass loss, but isn’t. Studying this world offers a new insight into exoplanet formation across the Universe.
The absence of Neptune-mass exoplanets closer to the host stars in exoplanetary systems has been a bit of a mystery. Their lack has been attributed to one of two things; photoevaporation – mass is lost through ionisation of gas by radiation which then disperses away form the ionising source or high-eccentricity migration – where the planets move through the planetary system as we have seen with some of the giant planets in our Solar System.
To distinguish between these two possibilities a team of astronomers led by Morgan Saidel from the California Institute of Technology investigated the origins of TOI-1259 A b which is a Saturn mass exoplanet. It is in a 3.48 day orbit around a K type star at a distance putting it on the edge of the so called Neptune desert. A region around a star wherein there are no Neptune sized planets.

TOI-837 b is a young Saturn-sized exoplanet with a massive core, observations findEuropean astronomers have performed photometric and spectroscopic observations of a distant giant exoplanet known as TOI-837 b. As a result, they found that TOI-837 b is a young Saturn-sized planet containing a massive core, which challenges current core formation theories.
