Tracing a decade of activity towards a yellow hypergiant. The spectral and spatial morphology of IRC+10420 at au scales
Evgenia Koumpia, R. D. Oudmaijer, W. -J. de Wit +3
The fate of a massive star during the latest stages of its evolution is highly dependent on its mass-loss history and geometry, with the yellow hypergiants being key objects to stu…
The accretion rates and mechanisms of Herbig Ae/Be stars
C. Wichittanakom, R. D. Oudmaijer, J. R. Fairlamb +3
This work presents a spectroscopic study of 163 Herbig Ae/Be stars. Amongst these, we present new data for 30 objects. Stellar parameters such as temperature, reddening, mass, lumi…
Resolving the MYSO binaries PDS 27 and PDS 37 with VLTI/PIONIER
E. Koumpia, K. M. Ababakr, W. J. de Wit +7
Binarity and multiplicity appear to be a common outcome in star formation. In particular, the binary fraction of massive (OB-type) stars can be very high. In many cases, the furthe…
A Statistical Spectropolarimetric Study of Herbig Ae/Be Stars
Karim Ababakr, Rene Oudmaijer, Jorick Vink
We present Halpha linear spectropolarimetry of a large sample of Herbig Ae/Be stars. Together with newly obtained data for 17 objects, the sample contains 56 objects, the largest s…
Linear spectropolarimetry across the optical spectrum of Herbig Ae/Be stars
K. M. Ababakr, R. D. Oudmaijer, J. S. Vink
We present the results of spectropolarimetric observations of 12 Herbig Ae/Be objects. Our data have the largest spectropolarimetric wavelength coverage, 4560 Å to 9480 Å, publishe…
Spectroscopy and Linear Spectropolarimetry of the early Herbig Be Stars PDS 27 and PDS 37
K. M. Ababakr, J. R. Fairlamb, R. D. Oudmaijer +1
The number of well-studied early-type pre-main-sequence objects is very limited, hampering the study of massive star formation from an observational point of view. Here, we present…
