Abstract:
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
(|λ|=4.0°±3.5°). 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.
Description:
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 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. See Section 2.7.

Note (1): For stars with observations from TRES, spectroscopic atmospheric
properties were derived using the Stellar Parameter Classification
code (SPC; Buchhave+ 2012, J/other/Nat/486.375).
Because not all of our targets have spectra from TRES or CHIRON, we
used the SpecMatch-Emp code (Yee+ 2017, J/ApJ/836/77) to derive
spectroscopic parameters for all our targets.
We also performed a new analysis of the Magellan/PFS spectrum using
the Zonal Atmospheric Stellar Parameters Estimator (ZASPE;
Brahm+ 2017MNRAS.467..971B 2017MNRAS.467..971B) code, holding logg fixed.
