Hunting for young exoplanets in stellar associations using TESS

For the vast majority of exoplanets’ hosts, the age is not well constrained and consequently, planet properties, demographics, and occurrence rates have been widely unmapped as a function of time. Discovering exoplanets in young associations and moving groups can shed light on these topics as they provide the opportunity to investigate planet formation and evolution in environments with well-defined ages. The Full-Frame Images of TESS offer a huge data mining archive of millions of light curves to investigate. We present the analysis of∼12k TESS light curves of stars, belonging to 41 young associations and moving groups, with ages spanning from 1 Myr to 680 Myr. We have extracted the light curves of young association members from the FFIs, corrected the systematic errors that affected them, and performed transit simulations to establish the performances of our technique to discover transit planet candidates. We report the detection of novel candidates exoplanets belonging to stellar associations with ages between 10 and 50 Myr.
