Abstract
[en] Hot subdwarfs are hot and small He-burning objects which experienced strong mass loss on the RGB. Therefore, these stars constitute excellent opportunities for addressing the question of the evolution of exoplanetary systems directly after the RGB phase. In this master thesis, I aimed to evaluate the capacities of K2 data to detect exoplanets around hot subdwarfs by performing injection-and-recovery tests on the K2 light curves corrected by K2sff and EVEREST detrending pipelines. Then, I applied the lesson learnt from those tests by performing an exoplanetary search on 48 K2 targets thanks to the SHERLOCK pipeline.
