Two Massive Jupiters in Eccentric Orbits from the TESS Full-frame Images

We report the discovery of two short-period massive giant planets from NASA's Transiting Exoplanet Survey Satellite (TESS). Both systems, TOI-558 (TIC 207110080) and TOI-559 209459275), were identified 30-minute cadence Full Frame Images confirmed using ground-based photometric spectroscopic follow-up observations TESS's Follow-up Observing Program Working Group. find that b, which transits an F-dwarf ($M_{*}=1.349^{+0.064}_{-0.065}\ M_{\odot}$, $R_{*}=1.496^{+0.042}_{-0.040}\ R_{\odot}$, $T_{eff}=6466^{+95}_{-93}\ K$, age $1.79^{+0.91}_{-0.73}\ Gyr$) with orbital period 14.574 days, has a mass $3.61\pm0.15\ M_{\rm J}$, radius $1.086^{+0.041}_{-0.038}\ R_{\rm eccentric (e=$0.300^{+0.022}_{-0.020}$) orbit. b G-dwarf ($M_{*}=1.026\pm0.057\ $R_{*}=1.233^{+0.028}_{-0.026}\ $T_{eff}=5925^{+85}_{-76}\ $6.8^{+2.5}_{-2.0}\ in (e=$0.151\pm0.011$) 6.984-day orbit $6.01^{+0.24}_{-0.23}\ J}$ $1.091^{+0.028}_{-0.025}\ J}$. Our also reveals long-term radial velocity trend for TOI-559, indicating long-period companion. The statistically significant eccentricity measured each system suggests these migrated to their current location through dynamical interactions. Interestingly, both are ($>3\ J}$), adding population by TESS. Prompted new detections high-mass planets, we analyzed known distribution hot warm Jupiters but no evidence multiple populations. TESS should provide near magnitude-limited sample transiting Jupiters, allowing future detailed studies.
