A dusty veil shading Betelgeuse during its Great Dimming
M. Montargès, E. Cannon, E. Lagadec +24
Red supergiants are the most common final evolutionary stage of stars that have initial masses between 8 and 35 times that of the Sun. During this stage, which lasts roughly 100,00…
VLTI-AMBER velocity-resolved aperture-synthesis imaging of Eta Carinae with a spectral resolution of 12000. Studies of the primary star wind and innermost wind-wind collision
G. Weigelt, K. -H. Hofmann, D. Schertl +26
Context. The mass loss from massive stars is not understood well. Eta Car is a unique object for studying the massive stellar wind during the LBV phase. It is also an eccentric bin…
Mid-infrared interferometry of the massive young stellar object NGC 2264 IRS 1
R. Grellmann, Th. Ratzka, S. Kraus +3
The optically invisible infrared-source NGC 2264 IRS 1 is thought to be a massive young stellar object (~10 Msun). Although strong infrared excess clearly shows that the central ob…
VLTI/AMBER spectro-interferometry of the Herbig Be star MWC 297 with spectral resolution 12 000
G. Weigelt, V. P. Grinin, J. H. Groh +12
Circumstellar disks and outflows play a fundamental role in star formation. Infrared spectro-interferometry allows the inner accretion-ejection region to be resolved. We measured i…
Strong near-infrared emission in the sub-AU disk of the Herbig Ae star HD163296: evidence for refractory dust?
M. Benisty, A. Natta, A. Isella +12
We present new long-baseline spectro-interferometric observations of the HerbigAe star HD163296 obtained in the H and K bands with the AMBER instrument at VLTI. The observations co…
Spatially resolving the hot CO around the young Be star 51 Ophiuchi
E. Tatulli, F. Malbet, F. Menard +6
51 Oph is one of the few young Be stars displaying a strong CO overtone emission at 2.3 microns in addition to the near infrared excess commonly observed in this type of stars. In…
