A giant planet candidate transiting a white dwarf

Resumen

The formation and evolution of planets in general is closely linked to the life of their host star. What happens to the planetary systems at the end stages of the life cycle of their star has been one of the questions that have received attention from a theoretical point of view but has had a lack of real life examples to study. Among more than 4000 known exoplanets to date only a few of these objects have been found orbiting around pulsars, but so far we have found nothing that resembles what our own solar system will be like long after the Sun leaves the main sequence.

In this talk we will discuss the recent announcement by A. Vanderburg et al. of a giant planet candidate detected by the transit method orbiting around a white dwarf. The candidate was discovered using data from the space-based NASA mission TESS and confirmed using GTC, Spitzer, and other ground-based facilities. We will talk about the role that GTC played in this discovery, the peculiarity of this candidate system, and the possibility of detecting atmospheres in rocky planets orbiting around white dwarfs.
