High contrast AO imaging observations of PZ Tel and its sub-stellar companion — •Markus Mugrauer and Christian Ginski — AIU Jena, Jena, Germany

We will present new high contrast AO imaging observations of the PZ Tel system, taken with NACO at the Paranal Observatory. Our new NACO astrometry confirms the companionship of PZ Tel B on a very high significance level. The orbital motion of the companion relative to its primary is clearly detected between all observing epochs with evidence for deceleration. Our new NACO astrometry, together with the previously taken one, allows a characterization of the orbit elements of the PZ Tel system.
