Abstract :
[en] Hot Jupiters are rarely accompanied by other planets within a factor of a few in orbital distance. Previously, only two such systems have been found. Here, we report the discovery of a third system using data from the Transiting Exoplanet Survey Satellite (TESS). The host star, TOI-1130, is an eleventh magnitude K-dwarf in Gaia G-band. It has two transiting planets: a Neptune-sized planet (3.65 ± 0.10 R[SUB]\oplus[/SUB]) with a 4.1 days period, and a hot Jupiter (1.50[SUB]-0.22[/SUB][SUP]+0.27[/SUP] R[SUB]J[/SUB]) with an 8.4 days period. Precise radial-velocity observations show that the mass of the hot Jupiter is 0.974[SUB]-0.044[/SUB][SUP]+0.043[/SUP] M[SUB]J[/SUB]. For the inner Neptune, the data provide only an upper limit on the mass of 0.17 M[SUB]J[/SUB] (3σ). Nevertheless, we are confident that the inner planet is real, based on follow-up ground-based photometry and adaptive-optics imaging that rule out other plausible sources of the TESS transit signal. The unusual planetary architecture of and the brightness of the host star make TOI-1130 a good test case for planet formation theories, and an attractive target for future spectroscopic observations.
