Multiplicity of young stars in and around R Corona Australis
R. Köhler, R. Neuhäuser, S. Krämer +3
The R CrA star-forming region has a small dark cloud with quite a number of protostars, T Tauri stars, and some Herbig Ae/Be stars, plus a number of weak-line T Tauri stars around…
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…
The T Tauri star RY Tau as a case study of the inner regions of circumstellar dust disks
A. A. Schegerer, S. Wolf, Th. Ratzka +1
We study the inner region of the circumstellar disk around the TTauri star RY Tau. Our aim is to find a physical description satisfying the available interferometric data, obtained…
The molecular and dusty composition of Betelgeuse's inner circumstellar environment
Guy Perrin, Tijl Verhoelst, Stephen T. Ridgway +6
The study of the atmosphere of red supergiant stars in general and of Betelgeuse (alpha Orionis) in particular is of prime importance to understand dust formation and how mass is l…
Evidence for dust accumulation just outside the orbit of Venus
Ch. Leinert, B. Moster
To contribute to the knowledge of dynamics of interplanetary dust we are searching for structures in the spatial distribution of interplanetary dust near the orbit of Venus. To thi…
High spatial resolution mid-infrared observations of the low-mass young star TW Hya
Th. Ratzka, Ch. Leinert, Th. Henning +3
We want to improve knowledge of the structure of the inner few AU of the circumstellar disk around the nearby T Tauri star TW Hya. Earlier studies have suggested the existence of a…
