Radiation hydrodynamic simulations of massive stars combined with linear pulsation theory revealed the presence of very regular low-amplitude radial pulsations. Such pulsations were encountered during the core hydrogen burning as well as during the early core helium burning stage of evolution. For selected model stars we present light curves in various passbands which are derived from a posteriori radiative transfer computations on radiation hydrodynamic models. The results are processed with the aim of guiding observations to identify and monitor such regularly pulsating variable massive stars in nature.
