We report high spatial resolution i ’ band imaging of the multiple T Tauri system LkH \alpha 262/LkH \alpha 263 obtained during the first commissioning period of the Adaptive Optics Lucky Imager ( AOLI ) at the 4.2 m William Herschel Telescope , using its Lucky Imaging mode .
AOLI images have provided photometry for each of the two components LkH \alpha 263 A and B ( 0.41 arcsec separation ) and marginal evidence for an unresolved binary or a disc in LkH \alpha 262 .
The AOLI data combined with previously available and newly obtained optical and infrared imaging show that the three components of LkH \alpha 263 are co-moving , that there is orbital motion in the AB pair , and , remarkably , that LkH \alpha 262-263 is a common proper motion system with less than 1 mas/yr relative motion .
We argue that this is a likely five-component gravitationally bounded system .
According to BT-settl models the mass of each of the five components is close to 0.4 M _ { \odot } and the age is in the range 1-2 Myr .
The presence of discs in some of the components offers an interesting opportunity to investigate the formation and evolution of discs in the early stages of multiple very low-mass systems .
In particular , we provide tentative evidence that the disc in 263C could be coplanar with the orbit of 263AB .
