Abstract
A close substellar companion has been claimed to orbit the bright sdB star HD 149382 with a period of 2.391d. In order to check this important discovery we gathered 26 high resolution spectra over 55 days with the HERMES spectrograph on the 1.2m 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.
