An Improved Model of SiO Maser Emission in Miras
M. D. Gray, M. Wittkowski, M. Scholz +3
We describe a combined dynamic atmosphere and maser propagation model of SiO maser emission in Mira variables. This model rectifies many of the defects of an earlier model of this…
Coordinated AMBER and MIDI observations of the Mira variable RR Aql
Iva Karovicova, Markus Wittkowski, David A. Boboltz +1
We have used near- and mid-infrared interferometry to investigate the pulsating atmosphere and the circumstellar environment of the Mira variable RR Aql. Observations were taken wi…
The structure of the protoplanetary disk surrounding three young intermediate mass stars. II. Spatially resolved dust and gas distribution
D. Fedele, M. E. van den Ancker, B. Acke +7
[Abridged] We present the first direct comparison of the distribution of the gas, as traced by the [OI] 6300 AA emission, and the dust, as traced by the 10 micron emission, in the…
Asymmetric silicate dust distribution toward the silicate carbon star BM Gem
Keiichi Ohnaka, Hideyuki Izumiura, Christoph Leinert +3
Silicate carbon stars show the 10 micron silicate emission, despite their carbon-rich photospheres. They are considered to have circumbinary or circum-companion disks, which serve…
VLTI monitoring of the dust formation event of the Nova V1280 Sco
Olivier Chesneau, Dipankar Banerjee, F. Millour +13
We present the first high spatial resolution monitoring of the dust forming nova V1280 Sco performed with the Very Large Telescope Interferometer (VLTI). Spectra and visibilities w…
Spatially resolved dusty torus toward the red supergiant WOH G64 in the Large Magellanic Cloud
Keiichi Ohnaka, Thomas Driebe, Karl-Heinz Hofmann +2
We present N-band spectro-interferometric observations of the red supergiant WOH G64 in the Large Magellanic Cloud (LMC) using MIDI at the Very Large Telescope Interferometer (VLTI…
