Abstract:
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 (RP=1.01-1.77RJ) and have masses that range from 0.85 to
6.33MJ. 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 (RP>1.7RJ, 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+0.28MJ 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.
Description:
The initial detection of the new planets came from data collected by
the Transiting Exoplanet Survey Satelliyte (TESS) mission. TESS images
the sky with a 24x96° field of view and observes the same stars
for about a month before moving on to observe a different region.
We obtained photometric follow-up observations on all five systems
from the TESS Follow-up Observing Program Working Group subgroup 1
(SG1) for seeing-limited photometry. Specifically, the follow-up comes
from the Las Cumbres Observatory (LCO) telescope network, Whitin
Observatory at Wellesley College, KeplerCam on the 1.2m telescope at
Fred Lawrence Whipple Observatory (FLWO), Brierfield Observatory, PEST
Observatory, C. R. Chambliss Astronomical Observatory (CRCAO) at
Kutztown University, Adams Observatory at Austin College, and Suto
Observatory. To schedule the photometric transit follow-up
observations, we used the TAPIR software package.
To confirm targets from TESS in the Northern hemisphere, we observed
TOI-628, TOI-1333, TOI-1478, and TOI-1601 with the Tillinghast
Reflector Echelle Spectrograph (TRES) on the 1.5m Tillinghast
Reflector. The telescope is located at the Fred L.Whipple Observatory
on Mt. Hopkins, AZ, and the spectrograph has a resolving power of
R=44000.
We obtained a series of spectroscopic observations with the 1.5m
SMARTS/CHIRON facility for TOI-640 and TOI-1478. Using the FEROS
spectrograph mounted on the 2.2m MPG telescope at La Silla observatory
in Chile, we obtained eight observations of TOI-1478. FEROS has
R=48000
TOI-1478 was observed with the CORALIE high-resolution spectrograph
(R=60000) on the Swiss 1.2m Euler telescope at La Silla Observatories,
Chile.
TOI-628 was monitored by Minerva-Australis (R=80000) using two or
three telescopes.
