TOI-375 velocity and light curves
Listed in IVOA Registry (Virtual Observatory)
Exoplanetary systems with multiple giant planets present an opportunity to understand planet formation, migration processes, and long-term system-wide dynamical interactions.
Description
We report the discovery and characterization of a unique multi-planet system hosting three gas giant planets orbiting the post-main-sequence star TOI-375. The innermost planet, TOI-375 b, was initially detected by the TESS mission, and then confirmed with photometric follow-up observations and radial velocity measurements obtained with FEROS and CHIRON.
The radial velocity data revealed the presence of two additional planetary candidates, TOI-375 c and TOI-375 d. We find that TOI-375 b is a hot Jupiter with an orbital period of 9.45469+/-0.00002 days, a mass of 0.745+/-0.053M_J_, a radius of 0.961+/-0.043R_J_, and an eccentricity of 0.087+/-0.042. The outer two planets have orbital periods of 115.5 and 297.9 days, and minimum masses of 2.11+/-0.22M_J_ and 1.40+/-0.28M_J_, respectively.

The discovery of TOI-375 as the first known system hosting three or more fully evolved gas giants, with at least one transiting planet, makes it an excellent candidate for testing formation and migration theories.
