Motivated by future gravitational wave observations, this study performs forecast analysis to constrain a possible time variation of the fine structure constant a. By considering mock data from standard sirens and current observations of strong gravitational lensing systems, it is found that future standard sirens observations can also play a significant role in the search for variations of a.
Motivated by future gravitational waves observations, we perform forecasts analysis to constrain a possible time variation of the fine structure constant (a) within the context of the so-called runaway dilaton model. For this purpose, some gravitational-wave standard sirens mock data within the perspective of Einstein Telescope and LISA mission were considered jointly with current strong gravitational lensing systems observations. We find that future standard sirens observations can also play an important role in the search for possible variations of a within the methodology presented in this work.
