| Summary:
We present the discovery of 30 transiting giant planets that were initially
detected using data from NASA’s Transiting Exoplanet Survey Satellite (TESS)
mission. These new planets orbit relatively bright ($G leq 12.5$) FGK host
stars with orbital periods between 1.6 and 8.2 days, and have radii between 0.9
and 1.7 Jupiter radii. We performed follow-up ground-based photometry, high
angular-resolution imaging, high-resolution spectroscopy and radial velocity
monitoring for each of these objects to confirm that they are planets and
determine their masses and other system parameters. The planets’ masses span
more than an order of magnitude ($0.17,M_J < M_p < 3.3,M_J$). For two
planets, TOI-3593 b and TOI-4961 b, we measured significant non-zero
eccentricities of $0.11^+0.05_-0.03$ and $0.18^+0.04_-0.05$
respectively, while for the other planets, the data typically provide a
1-$sigma$ upper bound of 0.15 on the eccentricity. These discoveries represent
a major step toward assembling a complete, magnitude-limited sample of
transiting hot Jupiters around FGK stars.
