  • We numerically investigate the dynamics of how a close stellar fly-by encounter of a symmetrical circumstellar planetesimal disc can give rise to the many kinds of asymmetries and substructures attributed to the edge-on dusty disc of β Pictoris. In addition we present new optical coronagraphic observations of the outer parts of the disc of β Pic, and report that the radial extent is significantly greater than was found in previous measurements. The north-easterly extension of the disc's mid… CONTINUE READING
