VizieR Online Data Catalog: THYME. V. Discovering a new stellar association (Tofflemire+, 2021)

Observations took place in Sectors 12 and 13 (2019 May 24 through July 17). During the Transiting Exoplanets Survey Satellite (TESS) extended mission. We obtained follow-up observations with the Spitzer Space Telescope to monitor two transits of HD110082b. These observations occurred on 2019 November 25 and December 5 as part of our time-of-opportunity program dedicated to young planet-host follow-up (Program ID14011, PI:Newton). On 2020 May 16, HD110082 was observed for ~7hr from the Las Cumbres Observatory Global Telescope (LCOGT) 1.0m network node at the Southern African Astronomical Observatory (SAAO) in Sutherland, South Africa. The observation centered temporally on an HD110082b transit, obtaining Sloan i'-band imaging using the 4096x4096pixel Sinistro CCD imager (0.39"/pixel).

We have discovered that HD110082 is part of a young stellar association we designate MELANGE-1.
