Abstract

We report the detection of a hot Jupiter (M-p = 1.75(-0.17)(+0.14) M-J, R-p = 1.38 +/- 0.04R(J)) orbiting a middle-aged star (log g = 4.152(-0.043)(+0.030)) in the Transiting Exoplanet Survey Satellite (TESS) southern continuous viewing zone (beta = -79 degrees.59). We confirm the planetary nature of the candidate TOI-150.01 using radial velocity observations from the APOGEE-2 South spectrograph and the Carnegie Planet Finder Spectrograph, ground-based photometric observations from the robotic Three-hundred MilliMeter Telescope at Las Campanas Observatory, and Gaia distance estimates. Large-scale spectroscopic surveys, such as APOGEE/APOGEE-2, now have sufficient radial velocity precision to directly confirm the signature of giant exoplanets, making such data sets valuable tools in the TESS era. Continual monitoring of TOI-150 by TESS can reveal additional planets and subsequent observations can provide insights into planetary system architectures involving a hot Jupiter around a star about halfway through its main-sequence life.
