DV Aquarii

DV Aquarii is a binary star system in the zodiac constellation of Aquarius, near the border with Capricornus. It has a peak apparent visual magnitude of 5.89, which is bright enough to be visible to the naked eye. The distance can be estimated from its annual parallax shift of $0.244$, yielding a separation of 291 light years.

This is a detached eclipsing binary system of the Beta Lyrae type. The orbital period for the system is 1.5755 days and the eccentricity is unknown and probably non-zero; the orbital inclination is estimated to be $10.3$. During the primary eclipse the magnitude drops to 6.25. It descends to 6.10 with the secondary eclipse (with 6.10 being brighter than 6.25). The pair have been identified as candidate Herbig Ae/Be stars, and catalogued as A-type shell stars.

A magnitude 10.8 star with the designation HD 358087 is a common proper motion companion. It is located at an angular separation of $83.18$ and has 78% of the Sun's mass. If it is gravitationally bound to the main system, the orbital period is estimated to be around 611,855 years

This star was a part of the obsolete constellation Norma Nilotica.
