Astronomers find planetary system with gas giant exoplanet and white dwarf companion

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an interesting extrasolar planetary system consisting of a K-dwarf host star, a Jupiter-sized planet and a white dwarf. The finding and parameters of the system, designated TOI-1259, were presented in a paper published January 7 on the arXiv pre-print repository.
