Are all Young Stars Disc Accretors
Vink, J.S.; Drew, J.E.; Harries, T.J.; Oudmaijer, R.D. (Astronomical Society of the Pacific, 2002)We demonstrate the importance of Ha spectro-polarimetry in constraining the geometry of Herbig Ae/Be stars. We find that discs are common in Herbig Ae and Be stars, although different polarization signatures may imply ... -
Binary star formation : Primary disks and secondary stars
Wheelwright, H.E.; Vink, J.S.; Oudmaijer, R.D.; Drew, J.E. (American Institute of Physics (AIP), 2012)Most intermediate mass, pre-main-sequence Herbig Ae/Be stars reside in binary systems. As they are young, the properties of these systems allow us to constrain how they form. We have investigated the formation of Herbig ... -

(2012-09-01)We describe the motivation, design, and implementation of the CORNISH survey, an arcsecond-resolution radio continuum survey of the inner galactic plane at 5 GHz using the Very Large Array (VLA). It is a blind survey ... -

(2013-03-01)The CORNISH project is the highest resolution radio continuum survey of the Galactic plane to date. It is the 5 GHz radio continuum part of a series of multi-wavelength surveys that focus on the northern GLIMPSE region ... -
Diffuse interstellar bands in the spectra of massive young stellar objects
Oudmaijer, R.D.; Busfield, G.; Drew, J.E. (1997)We have compared the B−V colour excess, E(B–V), obtained for a sample of five optically visible massive YSOs both from diffuse interstellar bands (DIBs) in their spectra and from their optical continuum slopes. Our targets ... -

Helium absorption and emission towards Theta^1 ORI C
Oudmaijer, R.D.; Drew, J.E.; Barlow, M.J.; Crawford, I.A.; Proga, D. (1997)The Hei absorption and emission systems towards Theta^1Ori C, the exciting star of the Orion Nebula, are investigated. To this end, high-resolution near-infrared long-slit spectra centred on the Hei 1.083-μm and Brgamma ... -
