Detection of rotational modulation in the lightcurves taken by the CoRoT, Kepler and TESS satellites allowed for the determination of a set of ideal candidates to observe using spectropolarimetry, with the goal of detecting magnetic fields around O, B and A-type stars.
In particular, we focused on variable stars, objects whose brightness varies over time due to pulsations. These stars are appealing to study, as the interactions between the magnetic field and pulsations allow us to enforce constraints on asteroseismological models and the internal structure of these stars.
Currently, only a handful of these objects have been studied, limiting our understanding of the physical processes occurring within these stars.. We hoped to contribute to the limited sample size of these objects, and eventually draw some conclusions between these stars and the types and strengths of the fields they present.
