Deep Optical Imaging of a Compact Group of Galaxies: Seyfert's Sextet
2000
Astronomical Journal
In order to investigate the dynamical status of Seyfert's Sextet (SS), we have obtained a deep optical (VR+I) image of this group. Our image shows that a faint envelope, down to a surface brightness μ_ optical(AB) ≃ 27 mag arcsec^-2, surrounds the member galaxies. This envelope is irregular in shape. It is likely that this shape is attributed either to recent-past or to on-going galaxy interactions in SS. If the member galaxies have experienced a number of mutual interactions over a long
