Title: Examining young binary systems in birth by high angular resolution 
observations

Abstract:
The aim of this project is to carry out a survey of young T Tauri binaries, 
which were discovered in the early 1990s using speckle interferometry or lucky 
imaging techniques. The aim of the first phase of this survey is to reobserve 
about 30 T Tauri pairs on the northern sky using a fast Andor iXon EMCCD camera 
mounted on the 1 m class RCC telescope at the Piszkéstető Mountain Station, 
Hungary, and determine whether the orbital motion of the companion could be 
revealed by using speckle interferometry or lucky imaging. The next phase of 
this project would cover more T Tauri targets, primarily targets that are 
available in the NACO or SINFONI archives, covering the southern sky and 
fainter objects.
