Abstract
Abstract We present the discovery of TIC-65910228 b / NGTS-38 b, a giant exoplanet with a radius of 1.081 ± 0.047 RJ and a mass of $4.77_{-0.37}^{+0.39}$ MJ on a long-period (180.52797 ± 0.00036 day), moderately eccentric (e=0.3086 ± 0.010) orbit transiting a bright (V=10.230 ± 0.020 mag) metal rich ([Fe/H]=0.33 ± 0.09 ‘dex’) F6V-F7V type host star. The planet was initially detected from a single transit in TESS Sector 33. A photometric monitoring campaign of 228 nights with NGTS detected a transit egress of the planet, which together with spectroscopic radial velocity monitoring with CORALIE and HARPS identified an orbital period of 180.5 d. These radial velocity measurements also showed the mass of the companion to be planetary. Additional transit observations coordinated by the TESS follow-up observing program allowed further confirmation and refinement of this period. With its relatively cool equilibrium temperature of 457 ± 11 K, NGTS-38 b joins a small but growing population of well characterised transiting warm-Jupiters and has one of the longest periods of any discovered to date. The target is situated in the LOPS2 field of the upcoming PLATO mission which will allow for greater refinement of the system parameters and potential for the discovery of additional companions too small and/or too long-period to be seen by TESS or NGTS. NGTS-38 b’s bright host star and wide orbital separation make it an attractive target for further study, including potential measurement of its spin-orbit alignment or targeted exomoon/ring searches.
