A Search for Exoplanets in Open Clusters and Young Associations based on
  TESS Objects of Interest
  We report the results of our search of planet candidates in Open Clusters and
Young Stellar Associations based on the TESS Objects of Interest Catalog. We
find one confirmed planet, one promising candidate, one brown dwarf, and three
unverified planet candidates in a sample of 1229 Open Clusters from the second
Gaia data release. We discuss individual planet-star systems based on their
basic parameters, membership probability, and the observation notes from the
ExoFOP-TESS website. We also find ten planet candidates (P $>$ 95%) in Young
Stellar Associations by using the BANYAN $\Sigma$ Bayesian Algorithm. Among the
ten candidates, five are known planet systems. We estimate the rotation periods
of the host stars using the TESS light curves and estimate their ages based on
gyrochronology. Two candidates with periodic variations are likely to be young
planets, but their exact memberships to Young Stellar Associations remain
unknown.
