A high-mass protobinary system with spatially resolved circumstellar accretion disks and circumbinary disk
Stefan Kraus, Jacques Kluska, Alexander Kreplin +9
High-mass multiples might form via fragmentation of self-gravitational disks or alternative scenarios such as disk-assisted capture. However, only few observational constraints exi…
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…
VLTI/AMBER spectro-interferometry of the late-type supergiants V766 Cen (=HR 5171 A), sigma Oph, BM Sco, and HD 206859
M. Wittkowski, B. Arroyo-Torres, J. M. Marcaide +3
We add four warmer late-type supergiants to our previous spectro-interferometric studies of red giants and supergiants. V766 Cen (=HR 5171 A) is found to be a high-luminosity log(L…
Mass Losing Asymptotic Giant Branch Stars and Supergiants
Patricia A. Whitelock, Martha Boyer, Susanne Höfner +2
This paper presents a summary of four invited and twelve contributed presentations on asymptotic giant branch stars and red supergiants, given over the course of two afternoon spli…
Planet Formation Imager (PFI): science vision and key requirements
Stefan Kraus, John D. Monnier, Michael J. Ireland +75
The Planet Formation Imager (PFI) project aims to provide a strong scientific vision for ground-based optical astronomy beyond the upcoming generation of Extremely Large Telescopes…
Near-infrared spectro-interferometry of Mira variables and comparisons to 1D dynamic model atmospheres and 3D convection simulations
M. Wittkowski, A. Chiavassa, B. Freytag +4
We obtained a total of 20 near-infrared K-band spectro-interferometric snapshot observations of the Mira variables o Cet, R Leo, R Aqr, X Hya, W Vel, and R Cnc with a spectral reso…
