Spatial and spectral constraints on resolved mass-loss of the massive Post-RSG star IRAS 17163-3907 and its Fried Egg Nebula
E. Koumpia, A. Cikota, W. -J. de Wit +12
The fate of massive stars during the latest stages of their evolution is highly dependent on their mass-loss rate and geometry. These processes have a significant influence on star…
The first interferometric survey in the K-band of massive YSOs. On the hot dust, ionised gas, and binarity at au scales
E. Koumpia, W. -J. de Wit, R. D. Oudmaijer +8
Circumstellar discs are essential for high mass star formation, while multiplicity, in particular binarity, appears to be an inevitable outcome since the vast majority of massive s…
Towards a physical understanding of the thermal background in large ground-based telescopes
Leonard Burtscher, Ioannis Politopoulos, Sergio Fernández-Acosta +11
Ground-based thermal-infrared observations have a unique scientific potential, but are also extremely challenging due to the need to accurately subtract the high thermal background…
A multi-scale exploration of a massive young stellar object - a transition disk around G305.20+0.21?
A. J. Frost, R. D. Oudmaijer, W. J. de Wit +1
The rarity of young massive stars combined with the fact that they are often deeply embedded has limited the understanding of their formation. Ground based mid-infrared (IR) interf…
Chasing discs around O-type (proto)stars - ALMA evidence for an SiO disc and disc wind from G17.64+0.16
L. T. Maud, R. Cesaroni, M. S. N. Kumar +28
We present high angular resolution 0.2 arcsec continuum and molecular emission line Atacama Large Millimeter/sub-millimeter Array (ALMA) observations of G17.64+0.16 in Band 6 (220G…
Multi-epoch VLTI-PIONIER imaging of the supergiant V766 Cen: Image of the close companion in front of the primary
M. Wittkowski, F. J. Abellan, B. Arroyo-Torres +10
The star V766 Cen (=HR 5171A) was originally classified as a yellow hypergiant but lately found to more likely be a 27-36 Msun red supergiant (RSG). Recent observations indicated a…
