8-499: A period of 130.5 days, or one half of their orbital period. The eclipse of the primary component causes a decline of 0.04 of a magnitude, while the secondary eclipse reduces the magnitude by 0.03. The combined stellar classification is K5 III, which matches the spectrum of a giant star . The primary is 44 times larger than the Sun and 340 times more luminous. Its surface has an effective temperature of 4,077 K , giving it

Their orbital period is 257.8 days and the eccentricity is 0.17. The pair form an eclipsing binary of the Beta Lyrae type and
16-410: The orange hue of a K-type star . It shows the behavior of a slow irregular variable . In addition to its binary components, Sigma Puppis has a more distant companion that has a matching proper motion , suggesting that it may be gravitationally bound to the binary. This magnitude 8.5 star is at an angular separation of 22.4 arcseconds with a position angle of 74° from Sigma Puppis, which
