Orbits and Masses in the T Tauri System
Rainer Köhler, Thorsten Ratzka, T. M. Herbst +1
We investigate the binary star T Tauri South, presenting the orbital parameters of the two components and their individual masses. We combined astrometric positions from the litera…
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…
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…
A VLT/NACO Survey for Triple and Quadruple Systems among Visual Pre-Main Sequence Binaries
S. Correia, H. Zinnecker, Th. Ratzka +1
This paper describes a systematic search for high-order multiplicity among wide visual Pre-Main Sequence (PMS) binaries. We conducted an Adaptive Optics survey of a sample of 58 PM…
Disks around young stars with VLTI/MIDI
Roy van Boekel, Peter Abraham, Serge Correia +17
We report on observations of circumstellar disks around young stars that have been obtained with the MIDI instrument, which is mounted on the VLT Interferometer and operates in the…
FU Orionis - The MIDI/VLTI Perspective
Sascha P. Quanz, Thomas Henning, Jeroen Bouwman +2
We present the first mid-infrared interferometric measurements of FU Orionis. We clearly resolve structures that are best explained with an optically thick accretion disk. A simple…
