VizieR Online Data Catalog: The TESS Grand Unified Hot Jupiter Survey I. 10 planets (Yee+, 2022)
Abstract
All of the new planets described here were first detected in Transiting Exoplanet Survey Satellite (TESS) photometry. TESS observes a 24x96deg region of the sky for 27days at a time, before rotating its field of view to a new sector.
We also used the ground-based light curves to refine the transit parameters and ephemerides. Observations were obtained from the Brierfield Observatory; KeplerCam on the Fred Lawrence Whipple Observatory (FLWO) 1.2m telescope; the Hazelwood Observatory; the Acton Sky Portal; the Villa '39 observatory; the Observatori Astronomic de la Universitat de Valencia (OAUV) TURIA2 0.3m telescope; the Grand-Pra Observatory; the Silesian University of Technology Observatories (SUTO) OTIVAR 0.3m telescope; the MEarth-South telescope array at the Cerro Tololo Inter-American Observatory (CTIO); as well as the 0.4m and 1.0m telescopes of the Las Cumbres Observatory Global Telescope (LCOGT) global network, using sites at the Observatorio del Teide, CTIO, the Siding Spring Observatory (SSO), and the South African Astronomical Observatory (SAAO). We observed TOI-2193, TOI-2207, and TOI-3331 with the Prime Focus Spectrograph (PFS) on the 6.5m Magellan II Clay Telescope at the Las Campanas Observatory in Chile. We observed each target in the 3x3 binning mode with the iodine cell in the optical path, choosing short exposure times of 10 minutes or less, which allowed us to attain a typical precision of about 5m/s, well above the instrument's demonstrated long-term precision of ~<1m/s. TOI-2207, TOI-2236, and TOI-2421 were observed with CHIRON on the Cerro Tololo Inter-American Observatory (CTIO) 1.5m telescope on Cerro Tololo in Chile. CHIRON is an optical, fiber-fed echelle spectrometer with a spectral resolution of R~80000 when used with an image slicer. We observed with typical exposure times of 1200-1800s, bracketed by calibration observations of a ThAr lamp. TOI-2207 was also observed on six epochs with the Fibre-Fed Optical Echelle Spectrograph (FEROS) mounted on the MPG 2.2m telescope at the ESO La Silla Observatory, in Chile. The six observations of TOI-2207 were performed between 2021-07-22 and 2021-10-24 with a typical exposure time of 1200 seconds, achieving an S/N per resolution element ranging from 70 to 100. We also obtained 11 observations of TOI-2421 between 2021-06-26 and 2021-08-16 using the Minerva-Australis telescope array, located at Mt. Kent Observatory, Australia. Minerva-Australis is an array of four identical 0.7m telescopes linked via fiber feeds to a single KiwiSpec echelle spectrograph at a spectral resolving power of R~80000 over the wavelength region of 5000-6300Å. We observed all five targets in the Northern hemisphere with the Tillinghast Reflector Echelle Spectrograph (TRES). TRES has a spectral resolution of R~44000 and is located on the FLWO 1.5m Tillinghast Reflector telescope on Mount Hopkins, Arizona. We observed TOI-2567, TOI-3540, and TOI-3693 with HIRES on the Keck I 10m telescope on Maunakea, Hawaii. We obtained six to nine observations for each target with an iodine cell that provides a precise wavelength calibration and allows for radial velocity extraction. These observations were made through the queue system operated by the California Planet Search (CPS). TOI-2570 and TOI-4137 were observed with the NEID spectrograph on the WIYN 3.5m telescope at Kitt Peak National Observatory (KPNO). NEID is a newly commissioned stabilized, fiber-fed optical spectrograph with a resolving power of R~110000 spanning the wavelength range from 3800 to 9300Å. (5 data files).- Publication:
