VizieR Online Data Catalog: TOI-815 light curves and RV sources (Psaridi+, 2024)
Abstract
The TOI-815 system (TIC 102840239) was observed in TESS Sector 9 (2018 December 12 to 2019 January 06) in 30-min cadence and Sectors 36 (2021 March 07 to 2021 April 01) and 63 (2023 March 10 to 2023 April 06) in 20-s cadence. In Sectors 9 and 36, the target was imaged on CCD 2 of camera 2, and in Sector 63, on CCD 1 of camera 2.
TOI-815 was jointly observed by two programs within the CHEOPS guaranteed time observation (GTO): one targeting improved radius precision for multi-planet systems detected by NASA TESS (CHESS; PR0031) and the other targeted on confirming the orbital periods of long-period candidates found by TESS (DUOS; PR0048). The observations had an exposure time of 60s, typical duration of 5-7 orbits (8.2-11.4h), and achieved efficiencies between 51 and 73% (e.g., due to Earth occultations, Earth's stray light contamination and South Atlantic Anomaly crossings). We observed TOI-815 with ASTEP on 2021 April 04 but could only rule out an ingress of TOI-815b that was, at the time, predicted to occur at BJD 2459309.02. We observed an intended full transit window of TOI-815b on 2021 February 18 in Pan-STARRS z-short band using the LCOGT 1.0m network node at South Africa Astronomical Observatory (SAAO). We acquired 34 high-resolution spectroscopic observations of TOI-815 using ESPRESSO on the 8.2m Very Large Telescope (VLT) located in Paranal, Chile. The observations were carried out between 2021 April 04 and 2022 December 04 as part of the observing programs 105.20P7.001, 109.23DX.001 and 110.2481.001 (PI: Bouchy), dedicated to the characterization of warm mini-Neptune transiting exoplanets. TOI-815 was also observed by the Wide Angle Search for Planets (WASP) Transit survey in multiple years between 2006 and 2014, with the observing season in each year spanning ~120 nights. A total of 86000 photometric data points was obtained using 200mm, f/1.8 Canon lenses until 2012 and 85mm f/1.2 Canon lenses after that. TOI-815 is by far the brightest star in the extraction aperture. (5 data files).- Publication:
