Abstract: |
We report on our follow-up program of a sample of young T
Tauri binaries, which were discovered in the early 1990s using speckle
interferometry or lucky imaging techniques. In the first phase of this
survey we plan to re-observe about 30 T Tauri pairs in the northern sky
using lucky imaging with the 1m RCC telescope at the
Piszkéstető Mountain Station, Hungary, or with the AstraLux Norte
system on the 2.2m telescope at Calar Alto. The long
baseline of more than 20 years gives us an opportunity to detect the
orbital motion of the companions. In some of the systems it may eventually
also be possible to determine the orbital parameters yielding
model-independent system masses. These masses complemented with spectroscopic
data can enable us to characterize the systems and examine the influence of
multiplicity on the evolution of planet-forming disks. |
