HD 61330 (f Puppis) is a class B8IV [3] (blue subgiant) star in the constellation Puppis. Its apparent magnitude is 4.53 [2] and it is approximately 360 light years away based on parallax. [1]

It is a multiple star, with a secondary component C, with magnitude 6.07 in an 81-year orbit with eccentricity 0.64. [7] Another closer component, B, has been reported at 6.1 magnitude and 0.1" separation, but subsequent observers have repeatedly failed to confirm it. [8]

<span class="mw-page-title-main">V Puppis</span> Variable star in the constellation Puppis

V Puppis is a star system in the constellation Puppis. Its apparent magnitude is 4.41. There is a binary star system at the center with a B1 dwarf orbiting a B3 subgiant star. They have an orbital period of 1.45 days and a distance of only 15 solar radii apart. However, the system moves back and forth, indicating that there is a massive object orbiting them with a period around 5.47 years. Based on the mass of the object, its lack of a visible spectrum, and circumstellar matter in the system with many heavy elements, it is probably a black hole. However, a follow-up study could not confirm this object, but found signs that there may be a third object which is fainter than the other components.
