Description
We present the discovery and characterization of five hot and warm Jupiters TOI-628b (TIC281408474; HD288842), TOI-640b (TIC147977348), TOI-1333b (TIC395171208, BD+473521A), TOI-1478b (TIC409794137), and TOI-1601b (TIC139375960)-based on data from NASA's Transiting Exoplanet Survey Satellite (TESS). The five planets were identified from the full-frame images and were confirmed through a series of photometric and spectroscopic follow-up observations by the TESS Follow-up Observing Program Working Group. The planets are all Jovian size (R_P_=1.01-1.77R_J_) and have masses that range from 0.85 to 6.33M_J_. The host stars of these systems have F and G spectral types (5595<~Teff<~6460K) and are all relatively bright (9.5<V<10.8, 8.2<K<9.3), making them well suited for future detailed characterization efforts. Three of the systems in our sample (TOI-640b, TOI-1333b, and TOI-1601b) orbit subgiant host stars (logg<4.1). TOI-640b is one of only three known hot Jupiters to have a highly inflated radius (R_P_>1.7R_J_, possibly a result of its host star's evolution) and resides on an orbit with a period longer than 5days. TOI-628b is the most massive, hot Jupiter discovered to date by TESS with a measured mass of 6.31_-0.30_^+0.28^M_J_ and a statistically significant, nonzero orbital eccentricity of e=0.074_-0.022_^+0.021^. This planet would not have had enough time to circularize through tidal forces from our analysis, suggesting that it might be remnant eccentricity from its migration. The longest-period planet in this sample, TOI-1478b (P=10.18days), is a warm Jupiter in a circular orbit around a near-solar analog. NASA's TESS mission is continuing to increase the sample of well-characterized hot and warm Jupiters, complementing its primary mission goals.
