We report the confirmation and mass determination of three hot Jupiters discovered by the Transiting Exoplanet Survey Satellite ( TESS ) mission : HIP 65Ab ( TOI-129 , TIC-201248411 ) is an ultra-short-period Jupiter orbiting a bright ( V =11.1 mag ) K4-dwarf every 0.98 days .
It is a massive 3.213 \pm 0.078 \mathrm { M } _ { J } planet in a grazing transit configuration with impact parameter b = 1.17 ^ { +0.10 } _ { -0.08 } .
As a result the radius is poorly constrained , 2.03 ^ { +0.61 } _ { -0.49 } \mathrm { R } _ { J } .
We perform a full phase-curve analysis of the TESS data and detect both illumination- and ellipsoidal variations as well as Doppler boosting .
HIP 65A is part of a binary stellar system , with HIP 65B separated by 269 AU ( 3.95 arcsec on sky ) .
TOI-157b ( TIC 140691463 ) is a typical hot Jupiter with a mass 1.18 \pm 0.13 \mathrm { M } _ { J } and radius 1.29 \pm 0.02 \mathrm { R } _ { J } .
It has a period of 2.08 days , which corresponds to a separation of just 0.03 AU .
This makes TOI-157 an interesting system , as the host star is an evolved G9 sub-giant star ( V=12.7 ) .
TOI-169b ( TIC 183120439 ) is a bloated Jupiter orbiting a V=12.4 G-type star .
It has a mass of 0.79 \pm 0.06 \mathrm { M } _ { J } and radius 1.09 ^ { +0.08 } _ { -0.05 } \mathrm { R } _ { J } .
Despite having the longest orbital period ( P = 2.26 days ) of the three planets , TOI-169b receives the most irradiation and is situated on the edge of the Neptune desert .
All three host stars are metal rich with \left [ { Fe / H } \right ] ranging from 0.18 - 0.24 .
