Planetary systems have been found systematically orbiting main sequence stars and red giants. But the detection of planets per se during the white dwarf phase has been more elusive with only 3 systems. We have, however, ample indirect evidence of the existence of planetary debris around these systems in the form of material acreted onto the white

The search for extrasolar planets is one of the fastest-growing fields of astronomy. This rapid growth was both made possible by the development of instrumentation and motivated it, creating a virtuous cycle that impacted positively several fields of research. In this talk I will present the latest planet-hunting spectrograph ESPRESSO, installed at

Stellar magnetic activity generates astrophysical noise on the collected data in the quest for what might be called Earth 2.0. This noise poses obstacles and difficulties in the detection and accurately determining small-sized exoplanets properties. Characterising the relation between stellar photometric variability and radial velocity jitter can
