[en] In 2013, we reported on the variability properties of zeta Puppis, one of the hottest and closest
massive stars. In particular, while short-term stochastic variability seems absent, ”trends” with a typical timescale longer than the exposure length were detected. Since then, such features were found in other objects as well, and the favored scenario links them to co-rotating wind structures. Using new observations as well as optical photometry, we revisit the variability of zeta Pup with the aim of assessing the CIR scenario.
