67 Ophiuchi is a class B5 Ib star in the constellation Ophiuchus. Its apparent magnitude is 3.93 and it is approximately 1200 light years away based on parallax. It is considered to be a member of the open cluster Collinder 359.

<span class="mw-page-title-main">Gamma Monocerotis</span> Star in the constellation of Monoceros

γ Monocerotis, Latinised as Gamma Monocerotis, is a binary star system in the equatorial constellation of Monoceros. Based upon an annual parallax shift of 6.55 mas, it is located roughly 500 light years from the Sun. It can be viewed with the naked eye, having an apparent visual magnitude of 3.96. Gamma Monocerotis is moving away from the Sun with a radial velocity of −5 km/s.

Zeta Monocerotis, Latinized from ζ Monocerotis, is a single, yellow-hued star in the constellation Monoceros. It has an apparent visual magnitude of 4.33, which is bright enough to be visible to the naked eye. The annual parallax shift as measured during the Hipparcos mission is 3.08 milliarcseconds, which provides a rough distance estimate of 1,060 light years. It is moving away from the Sun with a radial velocity of +30 km/s.

<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.
