Neutral and ionized gas around the post-Red Supergiant IRC+10420 at au size scales
Rene Oudmaijer, Willem-Jan de Wit
IRC +10420 is one of the few known massive stars in rapid transition from the Red Supergiant phase to the Wolf-Rayet or Luminous Blue Variable phase. The star has an ionised wind a…
CO bandhead emission of massive young stellar objects: determining disc properties
J. D. Ilee, H. E. Wheelwright, R. D. Oudmaijer +7
Massive stars play an important role in many areas of astrophysics, but numerous details regarding their formation remain unclear. In this paper we present and analyse high resolut…
AMBER and CRIRES observations of the binary sgB[e] star HD 327083: evidence of a gaseous disc traced by CO bandhead emission
H. E. Wheelwright, W. J. de Wit, G. Weigelt +2
HD 327083 is a sgB[e] star that forms a binary system with an orbital semi-major axis of ~1.7 AU. Our previous observations using the VLTI and AMBER in the medium resolution K-band…
Advances in understanding young high-mass stars using optical interferometry
W. J. de Wit
The closest examples of high-mass star birth occurs in deeply embedded environments at kiloparsec distances. Although much progress has been made, an observationally validated pict…
Chemical segregation toward massive hot cores: The AFGL2591 star forming region
I. Jimenez-Serra, Q. Zhang, S. Viti +2
We present high angular resolution observations (0.5"x0.3") carried out with the Submillimeter Array (SMA) toward the AFGL2591 high-mass star forming region. Our SMA images reveal…
Probing the envelopes of massive young stellar objects with diffraction limited mid-infrared imaging
H. E. Wheelwright, W. J. de Wit, R. D. Oudmaijer +4
Massive stars form whilst they are still embedded in dense envelopes. As a result, the roles of rotation, mass loss and accretion in massive star formation are not well understood.…
VLTI/AMBER observations of the binary B[e] supergiant HD 327083
H. E. Wheelwright, W. J. de Wit, R. D. Oudmaijer +1
HD 327083 is a luminous B type star which exhibits emission lines and an infrared excess and is therefore classified as a supergiant B[e] star. In addition, the star is the primary…
