HD 158259
HD 158259 is a main sequence star located  away in the constellation Draco. It hosts a system of at least five planets, discovered by the SOPHIE échelle spectrograph using the radial velocity method. Characteristics
HD 158259 is a G0 star with a rotation period of  days. More detailed analysis of the spectral assigns a class of G5V, but with the metal lines of an F9 star. Planets
Five planets have been confirmed orbiting HD 158259, along with one unconfirmed planet. These planets were discovered in 2019 by the radial velocity method, and the innermost planet, HD 158259 b, was also observed to transit the star by TESS. The planets orbit in a nearly 3:2 orbital resonance, with the period ratios 1.5758, 1.5146, 1.5296, 1.5130, and 1.4480, respectively, starting from the innermost pairing. A dynamical analysis has shown that the system is stable. One of the planets, HD 158259 b, is a super-Earth; the rest, including the unconfirmed HD 158259 g, are mini-Neptunes. References
