NW Puppis

NW Puppis, also known as υ2 Puppis, is a star in the constellation Puppis. Located around 910 light-years distant, it shines with a luminosity approximately 1,108 times that of the Sun and has a surface temperature of $18$. Anamarija Stankov ruled this star out as a Beta Cephei variable.

Neither component of this double is given a letter in Lacaille's catalogue or the British Association star catalogue. Gould gave them the designations (Latin letter) v1 and v2 Puppis, but these are rarely used. Lacaille applied the Greek letter υ to the star now called υ Carinae. The designation υ2 first appeared in several catalogues at the end of the 19th century.
