Abstract

Very Large Array1 observations of the two bright Herbig Ae/Be stars HD 163296 and HR 5999 have been carried out at λ3.6 and 20 cm. We report the detection of a radio source at λ3.6 cm that may be associated with HD 163296. From the peak flux density of 0.39 mJy/beam area, we estimate a mass-loss rate of 1.8 × 10-8script M signyr-1 if the flux is due to free-free emission in an ionized wind with spherical symmetry, assuming a terminal wind velocity of 200 km s-1. HR 5999 was not detected at either wavelength. We discuss the results in terms of the stellar-driven and accretion-driven scenarios for line and wind formation in Herbig Ae/Be stars.
