Astronomers discover a planetary system with a Neptune-mass planet and a massive sub-stellar object

An international team of astronomers reports the detection of a new planetary system by observing a nearby star known as HD 18599 (or TOI-179). It appears that this star is orbited by a Neptune-mass exoplanet and a massive sub-stellar object. The finding was detailed in a paper published October 14 on the arXiv pre-print server.
