Characteristics
Fragment disc in the view of the artist.
The star is a yellow-white main sequence dwarf. In 2006, studies of the star were carried out using the Spitzer orbital telescope [2] . The data showed that approximately at a distance of 10 AU. from Nu Phoenix is a cold fragmentation disk , similar to the Kuiper belt , consisting of cometary material. The data, however, are inaccurate, and more research is needed to confirm them.
