[en] I will talk about the opportunity to study planets/asteroids/debris discs around evolved stars with CHEOPS. Compact, post-red giant stars (subdwarf B stars and white dwarfs) will be part of the core program of TESS, which will provide, for the very first time, a census on the presence of planets/asteroids/debris discs around these stars. This will provide invaluable insights for the evolution of planetary systems and survival of close planets after the red giant phase. I will show how CHEOPS, with its larger collecting area and better sensitivity in the blue, could bring key added value to TESS for studying planets/asteroids/debris discs around evolved stars.
