VizieR Online Data Catalog: Radial velocity and transit photometry of TOI-1431 (Addison+, 2021)
Abstract
The star TOI-1431 was observed in Sectors 15 (on Camera 2 and CCD chip number 4) and 16 (on Camera 2 and CCD chip number 3) by Transiting Exoplanet Survey Satellite (TESS) in 2min cadence mode nearly continuously between 2019 August 15 and 2019 October 7.
One full transit of TOI-1431b was observed on 2019 December 24-25 with the CDK14 telescope at Howard Community College. The observations were taken using alternating 10s exposures in the Sloan g'an d z filters, starting at 23:02 UT on December 24 at an airmass of 1.2 and finishing at 02:56 UT on December 25 at an airmass of 2.4. Two full transits of TOI-1431b were observed with MuSCAT2, one on 2020 May 16 and a second one on 2020 May 24, using simultaneous multicolor photometry in g',r', i' and z bands. A full transit of TOI-1431b was observed with the 0.8m Prof. Dr. Berahitdin Albayrak Telescope (T80) at the AUKR on 2020 June 16 in the Sloan z band. We used the 0.3m telescope at the Kotizarovci Observatory near Viskovo, Croatia, to observe a full transit of TOI-1431b on 2020 August 8. On 2020 September 20, we observed a full transit of TOI-1431b from the 0.6m ULMT at Mt Lemmon using the Sloan z' filter. A full transit of TOI-1431b was observed on 2020 October 14 from the LCOGT 1.0m network node at McDonald Observatory near Fort Davis, Texas (LCO-McD), in PANSTARRS Y band. High-resolution spectroscopic observations of TOI-1431 were obtained using the robotic Stellar Observations Network Group (SONG) 1m Hertzsprung telescope at the Teide Observatory in Tenerife. (R=90000 between 4400 and 6900Å). TOI-1431 was observed with the fiber-fed SOPHIE HR echelle spectrograph on the 1.93m telescope at the Haute-Provence Observatory between 2019 December 18 and 2020 January 12. (R=75000 at 5500Å). We acquired 52 spectra of TOI-1431 using the Fibre-fed Echelle Spectrograph (FIES) at the 2.56m Nordic Optical Telescope (NOT) of Roque de los Muchachos Observatory (La Palma, Spain). (R=67000 at 3760-8220Å). We triggered observations of TOI-1431 on the Network of Robotic Echelle Spectrographs (NRES) operated by the LCOGT. (R=53000 between 380 and 860nm). We observed TOI-1431 with the Extreme Precision Spectrometer (EXPRES), which was recently commissioned at the 4.3m Lowell Discovery Telescope. (R~137500 between 380 and 780nm).
