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 ... -
Bayesian inference of T Tauri star properties using multi-wavelength survey photometry
Barentsen, G.; Drew, J.E.; Vink, J.S.; Sale, S.E. (2013-01-01)There are many pertinent open issues in the area of star and planet formation. Large statistical samples of young stars across star-forming regions are needed to trigger a breakthrough in our understanding, but most optical ... -
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 ... -

IPHAS discoveries of young stars towards Cyg OB2 and its southern periphery
Vink, J.S.; Drew, J.E.; Steeghs, D.; Wright, Nick; Martin, E.L.; Gansicke, B.T.; Greimel, R.; Drake, J. (2008)We report on the discovery of over 50 strong Hα emitting objects towards the large OB association Cyg OB2 and the H ii region DR 15 on its southern periphery. This was achieved using the INT Photometric Hα Survey of the ... -
