Low-amplitude rotational modulation rather than pulsations in the CoRoT B-type supergiant HD 46769
Low-amplitude rotational modulation rather than pulsations in the CoRoT B-type supergiant HD 46769
{We aim to detect and interpret photometric and spectroscopic variability of the bright CoRoT B-type supergiant target HD\,46769 ($V=5.79$). We also attempt to detect a magnetic field in the target.} {We analyse a 23-day oversampled CoRoT light curve after detrending, as well as spectroscopic follow-up data, by using standard Fourier …
