摘要：
Hot subdwarf stars are small post-red-giant-branch stars. To this day, no planets have been confirmed around them. In this document we present the first results of our analysis to quantify the presence of planets around hot subdwarfs by performing a wide transit survey using photometric data from the first part of the mission TESS. Our work shows an absence of transiting planets for the majority of these stars, but some display potentially interesting signals. These are now observed in our follow-up procedure. We also compute upper limits of the occurrence rates for planets around hot subdwarf stars from the numerous stars displaying no signal. © 2023 Societe Royale des Sciences de Liege.
