Searching for signals of transiting planets in the TESS light curves of white dwarfs with dust discs
Approximately 97% of stars will end their lives as white dwarfs. These stars are, therefore, the most common stellar remnants in our Galaxy. 1-3% of white dwarfs show an IR excess produced by a circumstellar dust disc, which is being accreted by the star. Such debris disc result of tidal disruption by rocky planetesimals that originally formed a planetary system. In this contribution, we present a photometric analysis with data from the TESS space mission of a sample of white dwarfs with dust discs, with the purpose of detecting possible events of transits of rocky bodies that have survived the evolution of the star.
