Abstract: A close substellar companion has been claimed to orbit the bright sdB star HD 149382 with a period of 2.391 d. In order to check this important discovery we gathered 26 high resolution spectra over 55 days with the HERMES spectrograph on the 1.2 m Mercator telescope on La Palma, and analyzed the resulting radial velocities. Our data show no sign of any significant radial-velocity periodicities, and from the high precision of our measurements we rule out any RV variations with amplitudes higher than 0.79 km/s on periods shorter than 50 days.
