CE Gruis is a (also known as Grus V-1) is a faint (magnitude 18–21) binary star system in the constellation Grus. It is composed of a white dwarf and donor star, in this case the two are so close and fused into orbit facing one another. Known as polars, material from the donor star does not form an accretion disc around the white dwarf, but rather streams directly onto it.^[2]
