Rd. Wolstencroft et al., PROPERTIES OF THE BETA-PICTORIS DISC DEDUCED FROM OPTICAL IMAGING POLARIMETRY, Astrophysics and space science, 224(1-2), 1995, pp. 395-398
The asymmetries in the brightness structure and levels of polarisation
between the two sides of the beta Pic disc are discussed. The possibi
lity of these differences being caused by a planet, or planets, within
the circumstellar disc is investigated.
