NASA's Transiting Exoplanet Survey Satellite (TESS) mission promises to improve our understanding of hot Jupiters by providing an all-sky, magnitude-limited sample of transiting hot Jupiters suitable for population studies. Assembling such a sample requires confirming hundreds of planet candidates with additional follow-up observations. Here we present 20 hot Jupiters that were detected using TESS data and confirmed to be planets through photometric, spectroscopic, and imaging observations coordinated by the TESS Follow-up Observing Program. These 20 planets have orbital periods shorter than 7 days and orbit relatively bright FGK stars (10.9<G<13.0). Most of the planets are comparable in mass to Jupiter, although there are four planets with masses less than that of Saturn. TOI-3976b, the longest-period planet in our sample (P=6.6 days), may be on a moderately eccentric orbit (e=0.18+/-0.06), while observations of the other targets are consistent with them being on circular orbits. We measured the projected stellar obliquity of TOI-1937A b, a hot Jupiter on a 22.4hr orbit with the Rossiter-McLaughlin effect, finding the planet's orbit to be well aligned with the stellar spin axis (|{lambda}|=4.0{deg}+/-3.5{deg}). We also investigated the possibility that TOI-1937 is a member of the NGC 2516 open cluster but ultimately found the evidence for cluster membership to be ambiguous. These objects are part of a larger effort to build a complete sample of hot Jupiters to be used for future demographic and detailed characterization work. |

TESS Grand Unified Hot Jupiter Surveys. II. [Dataset]Pozuelos, Francisco J.https://cdsarc.cds.unistra.fr/vizier/catstd/ADCkwds.htxExoplanetsPhotometry, UBVRIRadial velocitiesSurveysNASA's Transiting Exoplanet Survey Satellite (TESS) mission promises to improve our understanding of hot Jupiters by providing an all-sky, magnitude-limited sample of transiting hot Jupiters suitable for population studies. Assembling such a sample requires confirming hundreds of planet candidates with additional follow-up observations. Here we present 20 hot Jupiters that were detected using TESS data and confirmed to be planets through photometric, spectroscopic, and imaging observations coordinated by the TESS Follow-up Observing Program. These 20 planets have orbital periods shorter than 7 days and orbit relatively bright FGK stars (10.9<G<13.0). Most of the planets are comparable in mass to Jupiter, although there are four planets with masses less than that of Saturn. TOI-3976b, the longest-period planet in our sample (P=6.6 days), may be on a moderately eccentric orbit (e=0.18+/-0.06), while observations of the other targets are consistent with them being on circular orbits. We measured the projected stellar obliquity of TOI-1937A b, a hot Jupiter on a 22.4hr orbit with the Rossiter-McLaughlin effect, finding the planet's orbit to be well aligned with the stellar spin axis (|{lambda}|=4.0{deg}+/-3.5{deg}). We also investigated the possibility that TOI-1937 is a member of the NGC 2516 open cluster but ultimately found the evidence for cluster membership to be ambiguous. These objects are part of a larger effort to build a complete sample of hot Jupiters to be used for future demographic and detailed characterization work.The 20 planets described in this paper were first identified as transiting planet candidates in the TESS photometry. Following the conclusion of its Prime Mission in July 2020, TESS reobserved most of the sky as part of the first Extended Mission (EM1). Six of our targets (TOI-1937b, -2583b, -3807b, -3819b, -3912b, and -4087b) were identified as planet candidates based on Prime Mission data and selected for 2 minute cadence observations during EM1. The remaining objects continued to be observed as part of the FFIs, which are available with a 10 minute cadence in EM1. See Section 2.1. Two of our targets, TOI-2583b and TOI-2803b, were also detected as planet candidates by the WASP transit search (Pollacco+ 2006PASP..118.1407P). The WASP survey comprises two wide-field camera arrays at the Observatorio del Roque de los Muchachos on La Palma and the Sutherland Station of the South African Astronomical Observatory (SAAO). TOI-2583 was observed by WASP between 2004 and 2010, while TOI-2803 was observed between 2006 and 2012, with the transit events detected at the same period as those found by TESS. In addition to TOI-2583 and TOI-2803, archival WASP photometry was also available for TOI-2587, TOI-3364, TOI-3819, TOI-3912, and TOI-3976. See Section 2.2. Apart from the TESS and archival WASP photometry, we obtained additional light curves from a wide range of ground-based facilities, organized by the TFOP Seeing-limited Photometry Sub-Group 1. We summarize all the ground-based follow-up photometry in Table 3. See Section 2.3. As part of follow-up observations coordinated by the TFOP High-Resolution Imaging Sub-Group 3 (SG3), we obtained high angular-resolution imaging of all the targets described here. Observations, spanning 2020-Mar-13 to 2022-May-21 were made using several telescopes. These imaging observations are summarized in Table 4. See Section 2.4. In order to confirm each planetary candidate and measure its mass, we obtained high-resolution spectroscopy of their host stars. These observations (spanning 2006-Oct-20 to 2022-Aug-23) are summarized in Table 5. See Section 2.5. To ensure we have a complete view of each planetary system, we gather information about each target from the literature. We obtained photometric and astrometric observations from the TESS Input Catalog (TIC; see IV/38 and IV/39), Gaia DR3 (see I/355), 2MASS (see II/246), WISE (see II/311), and Tycho-2 (see I/259) catalogs. See Section 2.6. Finally, we observed a transit of TOI-1937Ab on the night of 2020-December-29 both spectroscopically and photometrically, in order to measure the projected stellar obliquity through the Rossiter-McLaughlin effect. The photometric observations were acquired from El Sauce, and the spectroscopy was acquired using Magellan/PFS. The photometric results are shown in Figure 15, with the transit occurring at the expected time.
