Abstract: The planet-hosting star GJ 436 has been extensively observed over the last months, including both spectroscopic and photometric data. Here we review the last studies and comment the validity of the scenario of a close-in perturber in GJ 436, concluding that it is not only plausible, but, in our opinion, is also the most likely to explain the observations.
