HD 110073
HD 110073 is a star in the southern constellation Centaurus, near the southern constellation border with Crux. It has the Bayer designation "l Centauri" (lower case L), while "HD 110073" is the star's identifier from the "Henry Draper catalogue". This system is faintlyvisible to the naked eye with an apparent visual magnitude of +4.63. It is located at a distance of approximately 365 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +15 km/s.

This is a single-lined spectroscopic binary star system that belongs to the Pleiades stream. As of 2011, the pair had a linear projected separation of . The primary component is a mercury-manganese star with a stellar classification of B8II/III. These stars are often helium-weak, but this is one of the most normal members of this group in terms of helium abundance. The system is a source for X-ray emission, which is most likely coming from the lower mass companion – it may even be a pre-main-sequence star.
