A photometric study of the peculiar and potentially double ringed,
  non-barred galaxy: PGC 1000714
  We present a photometric study of PGC 1000714, a galaxy resembling Hoag's
Object with a complete detached outer ring, that has not yet been described in
the literature. Since the Hoag-type galaxies are extremely rare and peculiar
systems, it is necessary to increase the sample of known objects by performing
the detailed studies on the possible candidates to derive conclusions about
their nature, evolution, and systematic properties. We therefore performed
surface photometry of the central body by using the archival near-UV, infrared
data and the new optical data (BVRI). This current work has revealed for the
first time an elliptical galaxy with two fairly round rings. The central body
follows well a r^(1/4) light profile, with no sign of a bar or stellar disc. By
reconstructing the observed spectral energy distribution, we recover the
stellar population properties of the central body and the outer ring. Our work
suggests different formation histories for the galaxy components. Possible
origins of the galaxy are discussed, and we conclude that a recent accretion
event is the most plausible scenario that accounts for the observational
characteristic of PGC 1000714.
