Scientific paper

With photoelectric photometry in the VBLUW system the authors have tried to detect short period brightness fluctuations in solar-like stars. Although the result of this experiment is negative, the r.m.s. noise level per frequency band of ca. 2.5×10-5 mag in the data appears low enough to encourage the ground-based search for low-1 p-mode oscillations in F-type main sequence stars.
